We're excited for today's content, and with that, I'll turn it over to Mark to start us off.
Thank you, Jacqueline. I'm excited to present the following session on Design Evolution with a focus on simulation-driven and generative design technologies introduced in Creo. The goal of this session will be to showcase how you can optimize your design process and leverage both simulation-driven and generative design tools to enhance your existing design workflows. In the end, you'll get a glimpse of the tools in action and provide the knowledge that can empower you to optimize your designs and drive innovation, making your work more impactful and valuable in today's dynamic market. My name is Mark Fischer, and joining me today is Todd Kraft. Both Todd and I are members of the Creo Product Management Team at PTC, and jointly, we'll present the transformational potential of simulation-driven and generative design methodologies seamlessly integrated in Creo. Let's kick things off with simulation-driven design.
Todd, can you showcase how the Ansys and PTC collaboration empowers rapid iterations within Creo? Can you demonstrate how both Creo Simulation Live and Creo Ansys Simulation can be used to transform the design process for unparalleled efficiency and innovation?
Thank you, Mark, for that introduction. During this opening session covering simulation-driven design, I will present an overview of our Ansys solutions within Creo and our latest enhancements. I'll then provide a few demonstrations to show you how amazing the integration of Ansys technology is with the Creo design environment. Let's first define what simulation-driven design is. Simulation-driven design is basically taking the simulation step that in the past was in the middle or late in the process and shifting it to the left and putting it at the front end of the development process when concept and design work is happening. Now we are letting simulation play a role in the design process to help guide decisions whether a specific change has a positive or negative effect on the design's function.
As indicated by this graphic, we have Creo Simulation Live playing that initial role for real-time guidance with groundbreaking GPU-enabled technology. Next, when things need more refinement, a user can then reuse all the setup they have done with CSL and take it into Creo Ansys for more sophisticated and powerful capabilities. Lastly, all the work they have done up to now can be preserved and taken into flagship Ansys products for further analysis options and then take advantage of the entire Ansys portfolio. Creo Simulation Live is created specifically for design engineers where the simulation results update dynamically in real time as you edit, create new features, or change material properties. It runs truly integrated within your design environment. No exports, no copies, no extra files, just design and gain insight as you work. It's easy to use, very simple to define your boundary conditions.
Let's describe the different physics that are covered with CSL. First is structural, identifying stresses, strains, deflection, and many more types of results. You can then use thermal studies to analyze the effects of heat or cold on your design. Next, you can evaluate and predict the natural frequencies of your system and associated mode shapes with modal simulation. Lastly, with fluid flow simulation, you can extract internal and external fluid bodies and simulate to look at streamlines, vectors, cross-sections, and various types of results for velocity, pressure, and more. All these capabilities provide benefits such as catching problems faster, reducing prototypes, and developing more innovative designs. Each release of Creo implements the most recent solver from Ansys. In addition, some of the specific features we've added recently are the support of multiple physics, which combine thermal and structural boundary conditions within one study.
This can be useful for looking at thermal expansion within the system. We implemented steady-state fluids in Creo 8 to provide a very accurate result for this type of simulation. Creo Simulation Live fluids is now able to simulate the complex geometry of formula-driven lattices such as gyroids, opening up many opportunities to perform fluid simulation on lattice geometry such as heat exchangers or other designs which take advantage of this kind of geometry. In Creo 9.0.1.0, we now have contact simulation providing greater accuracy over how components interact with each other in an assembly. We have also implemented surface regions in Core Creo, which enables you to use these in CSL for applying more accurate boundary conditions. Lastly, we provided more result types for fluid and structural studies. Let's now take a look at some of the recent Creo Simulation Live enhancements.
Let's take a look at this electric motor to show you the new enhancements for Creo Simulation Live in Creo 10.0. First, we'll change to a simplified rep for the geometry that we're going to use. Now we can create our boundary conditions for this structural study. The fixed constraint will be on the front surface, and we will define a free displacement constraint on this back surface. For our load, we'll create a global centrifugal load along the Z-axis at 1,400 RPM. Now, what's new in Creo Simulation Live in 9.0.1.0 is to define contacts between components. This provides much higher accuracy and provides contact stress for results. I can detect contacts automatically or define some tolerance values. Our entire contact detection was overhauled and improved in Creo 10.0. Now we simulate and look at the results.
Here are some Von Mises stress results, and next we can look at deformation. In Creo 10.0, we have two new results in structure. One is per strain, where we can look at principal or directional strain, and the other is contact stress. Here are those shown in this model. Next, let's move over to some new enhancements on the CSL fluid side with this electric motor and look at some cooling options. The first thing we need to do is define the fluid body, and we will use our automatic fluid extraction tool for that. Next, we define water as our material. Now we can apply our boundary conditions. We'll use mass flow inlet for the input, and we'll use an outlet on the other side of an output of zero pressure. We can click run to see the results. We will look at velocity and pressure first.
The new results for Creo Simulation Live fluids is looking at vectors for results. I have many controls for this: count, width, length, and more. Also, I can animate the vectors. Next, let's take a look at another cooling option for a fluid flow in this part. The geometry is set up for me already. I just need to suppress what I've done up to this point and resume the previous setup. For this model, it would be more of a helix type of fluid shape covering more surface area. All I have to do is tell it that this is going to be water as well, and then I can click on run and see the simulation. Let's go ahead and look at the same velocity results as vectors as we previously looked at.
Here in Creo 10, we have made improvements in CSL to help you get more accurate results and visually see the results better. CSL in Creo 10.0 also has been updated to the Ansys 22R2 solver. We can continue to see the animations, and also you can see our probes update when the fluid simulation is fully converged. Next, let's move on to Creo Ansys Simulation, which extends the partnership with Ansys to provide high-fidelity Ansys-powered technology in Creo that provides high accuracy for the validation phase of the design process. With Creo Ansys, you can solve structural, thermal, and modal simulations with support for many idealizations such as massive springs, shells, and beams. Beginning with Creo 7.0.2.0, we have continued to invest in Creo Ansys by updating the solver in each release of Creo and adding powerful capabilities for the design engineer.
If prior analysis was done using Creo Simulation Live, the analysis setup information is directly applied to studies when using Creo Ansys Simulation. For Creo Ansys Simulation in Creo 9.0, we have continued to refine our offering. For customers building thin-walled products, the simulation times can be significantly reduced by taking advantage of shell and beam elements. Consequently, in Creo 9, we have introduced the ability to automatically extract mid-surfaces from the design components and automatically define connections between those shell elements and perform a beam, shell-based, or entirely mixed-mesh simulation. This significantly reduces the time taken to calculate the results, enabling customers to build better products faster.
We also have introduced support for bearing loads, applying the loads normal to the surface to more accurately represent the real-world interaction of bearings, as well as adding support for inertia relief, the ability to perform a simulation on an unconstrained part or assembly. Finally, we have made numerous usability improvements throughout the product and updated the solver in Creo Ansys to match the latest Ansys solver available. In Creo 10.0, Creo Ansys crossed a milestone by delivering a new extension called Creo Ansys Simulation Advanced. With this new extension, we delivered three very powerful capabilities. First, Creo Ansys Simulation Advanced has non-linear contact, including frictional, frictionless, and rough. Each of these new contact types includes multiple behavior options such as formulation method, contact detection options, normal stiffness, and more. The second capability is non-linear materials. Now Creo Ansys can enter the plasticity range of simulation with bilinear material properties.
Also included are neo-Hookean, hyperelasticity, and linear orthotropic elasticity. These new material types expand the power of Creo Ansys use cases that can be solved. The last capability within this new advanced extension is combined physics of thermal and structure. In addition to these advanced capabilities within Creo 10.0, we have a new method implemented for contact detection, which makes defining contacts incredibly faster and more efficient than past revisions. Lastly, we have updated to the latest Ansys solver with Ansys 22R2. Before the Creo Ansys demonstration, let me review what I believe are the top five capabilities of PTC's Ansys-powered solutions. First is it's fully associative to Creo and integrated with the PTC digital thread, design iterations inside of Creo parametric with no data transfers, and it enables true simulation-driven design. Second, a familiar UI for Creo users.
No need to learn additional workflow or UI, and it works in part mode and assembly mode, any place that you want to work. Third, material properties and boundary conditions are stored within the Creo model and tracked in PTC Windchill. Fourth, incredible live technology developed by Ansys, fast and accurate. Lastly, more complex and traditional approaches with Creo Ansys, including non-linear capabilities inside of Creo 10.0. Let's now take a look at some of the recent Creo Ansys enhancements, and then I will pass the presentation back to Mark Fischer to cover Creo generative design technologies. Let's take a look at the same electric motor to show you a new enhancement within Creo Ansys in Creo 10.0. We now support multi-physics simulation within the Creo Ansys Simulation Advanced package.
If you have a thermal study, you can include structural constraints and forces, or if you have a structural study, you can include thermal boundary conditions and loads. You can see them all in the ribbon now. Here, you can see that this motor has a mixture of structural and thermal boundary conditions, including heat loads, a centrifugal force, and convection conditions, along with some structural boundary conditions for fixed and displacement. Here we can hide a component at the front and take a look at the more internal parts of the model, and also hide our simulation entities. There are appropriate contacts created between the components, and also let's take a look at the default mesh for this model. In this case, we've already run this model, so let's review some of the results. Here are the temperature results for the entire assembly due to the heat loads.
This is the entire assembly. We can also take a look at the thermal results or temperatures for the internals. Also, let's look at the thermal expansion for the assembly and also the thermal expansion for the internal parts. Lastly, we can review the stresses from the thermal loads in the model for the assembly and also very similar thermal stresses for the internal components. Multi-physics within Creo Ansys Simulation Advanced package brings the user many easy-to-use features to help explore results to improve customer designs. Let's take another look at the electric motor where the housing and shield come together to form a seal. This example will demonstrate the new non-linear contact options and non-linear materials in the Creo Ansys Simulation Advanced package. This example will be compressing a rubber seal between these two parts.
For the material definition, we are choosing a material from the Creo material database called Silicone Rubber, which has a hyperelastic definition. Since this example is axisymmetric, we can cut this into a wedge and simulate it with the appropriate boundary conditions. We've already set this model up, so let's take a look at what has been done. First, we've defined some frictionless constraints to handle the symmetry and keeping it in plane when we make the compression happen. Next, we have a displacement constraint where we have entered 0.35 mm to close the gap and compress the seal. In Creo Ansys Simulation Advanced, we have added three new types of non-linear contacts in Creo 10.0. This simulation has two different types of frictional contacts defined. Here we can look at all the options that Creo Ansys has for defining these contacts.
Next, we'll take a look at the second frictional contact. We have selected Augmentin deGrange for the formulation of both of these and varied the normal stiffness value. There are three contacts defined for this model. In Creo 10.0, you can now create multiple references for each contact, which makes contact definition much faster and more efficient. This model has one mesh control to make the rubber seal have finer elements. Here is what the mesh looks like for this example. This model has already been run, so we can now look at the results. The first two results will be the Von Mises stress results for the assembly, and then we can take a look at only the rubber seal Von Mises stress results. The new non-linear contact options provide many new result types. One of those is pressure, which we can look at next.
Lastly, we can look at the displacement results for the assembly and also with the rubber seal isolated. In Creo 10.0, the Creo Ansys Simulation Advanced package contains many new features, which expands the possible use cases for advanced customer designs. In the power connector for the electric motor, we can further highlight the Creo 10.0 non-linear materials and non-linear contact enhancements. First, we will define a non-linear material for this metal to have a bilinear type of elastoplastic response. The only change we need to make here for the material is to have a tangent modulus value. Next, we will make an assembly cut where we are left with a quarter of the geometry to help make the simulation run faster. There is a 2.7 mm gap, which will be displaced during the simulation. Now we can enter Creo Ansys and define our boundary conditions.
Let's hold it fixed here and add a displacement of 100 mm to the surface on the other connector, which is being inserted. Next, we add our frictionless supports to help define the symmetry by picking on the surfaces which were left after the cut. Now we can define a new non-linear contact. We will define the behavior first and then enter a new coefficient and a normal stiffness, leaving the rest of the definition box to be default. When we add the new contact, you can see how much quicker the process is in Creo 10.0 by selecting multiple references. In previous releases, we could only select one surface to one surface for each contact definition. This example would have had 12 contacts, where today in Creo 10.0, I only need to make one. I have already run this simulation, so let's change to that simulation model.
We have defined a few mesh controls to have more elements in a few critical areas. Here is what the mesh looks like for these components, adding many elements into the small areas of the connector. Let's look at the results now. First, we will look at equivalent plastic strain. We can see here that this model has used the non-linear material properties which were defined. Next, we can look at displacement and finally Von Mises stress for the entire assembly. This concludes my section of the presentation. I hope you've seen some very powerful Ansys-powered capabilities with non-linear materials and non-linear contacts. Now I'll hand it back to Mark for his section of today's presentation.
Thanks, Todd, for sharing and demonstrating the Ansys tools integrated into Creo and how they can be used to transform the design process. The next section I'd like to cover is generative design.
During this section, I'll present an overview of generative design, discuss the integrated capabilities in Creo and the connection to the cloud for high-performance computing. For those not familiar with generative design, I'll walk through a brief demonstration of the capabilities and then showcase the new enhancements introduced in the past several releases of Creo. PTC first introduced AI-driven generative design within the Creo design environment of Creo 7.0. Generative design is a means of autonomously creating optimal designs from a set of system design requirements, such as loads, constraints, preferred materials, but more importantly, manufacturing processes. It will unleash digital transformation across the entire enterprise, and its capabilities will allow manufacturers to drive workforce productivity by proactively addressing the user skill gaps. Using this solution, an entry-level mechanical engineer can rapidly generate innovative, high-quality designs, solving for specific design criteria and objectives.
It will reinvent the way next-generation designs are created, eliminating carryover geometry and reducing reliance on engineering experience and expertise. In addition, the solution will allow engineers to explore traditional and advanced manufacturing techniques, helping to create differentiated products, improve productivity, and create competitive differentiation. Lastly, generative design will help challenge assumptions and deliver high-quality, lower-cost, and manufacturable solutions. PTC offers two modules for generative design. The first module, which is fully integrated into the Creo design environment, is called Creo Generative Topology Optimization. GTO uses artificial intelligence to automatically generate the optimal design, solving for functional objectives, constraints, loads, and manufacturing process criteria. There are two main manufacturing scenarios that define a typical workflow when using generative design. The first scenario supports low-volume manufacturing of R&D prototypes, custom, and specialized products.
For this use case, manufacturing cost is not a concern due to low volumes and high price premiums for specialized and custom products. In this workflow, the results for generative design are directly used for the direct digital manufacturing or 3D printing of the products. The second scenario supports high-volume manufacturing. For this use case, there is a need to lower manufacturing costs and increase profits for high-volume products. To reduce costs and drive profitability, the results for generative design are recreated and refined in Creo to improve the design and manufacturability of the products. Let's take a look at the workflow. The first step is setup, where Creo users can quickly define a generative design optimization study, which can include one or multiple design scenarios.
During the setup, users will leverage familiar tools to define geometry, loads, and constraints, specify different manufacturing processes such as additive manufacturing, milling, casting, or forging. Leveraging patent volumetric geometry solvers and GPU processing, the optimization will solve quickly in front of your eyes, resulting in an optimized shape based on the design requirements. When optimizing the design, only one scenario or design criteria can be solved at one time. However, users can easily edit the requirements and output a new solution. Once the optimization is complete, users can automatically convert the optimized shape into rich B-Rep geometry through the reconstruction tools in Creo without the need to manually create any geometry. As a fully reconstructed Creo model, users can leverage the design in downstream processes such as analysis or manufacturing. The second module, which will leverage the optimization study created in GTO, is called Creo Generative Design Extension.
GDX is a cloud-based solution powered by PTC's SaaS platform, and it will allow users the ability to automatically produce and evaluate multiple optimization design alternatives through high-performance computing. From within GTO, users will be able to upload their complete study containing the defined requirements in one or many design scenarios. The cloud platform will simultaneously calculate all possible study solutions with different materials, parameters, or manufacturing processes. This is not a batch process. The powerful AI-based optimization engine will use search and machine learning to optimally find the best potential design for the users. Once calculated, users will be able to easily filter and compare the results, or if needed, refine the solution to compute new alternatives. For the desired solutions, users will be able to download the results to Creo, reconstruct, and generate a rich B-Rep geometry part. Let's walk through this workflow in a live demonstration.
On the screen is a sample bracket part, which we'll use to demonstrate the generative design workflow. Available under the applications tab, we can select generative design. To start with, we need to go specify the specific design spaces: starting geometry, preserve geometry, and exclude geometry. For this, we'll leverage the multi-body capabilities inside of Creo Parametric. Selecting the starting geometry, we can now choose one of the specific bodies. In this case, I'll choose E and V. Immediately, it makes the starting geometry transparent, which represents the area where the geometry is going to be optimized within. Second, we'll choose the preserve geometry. The preserve geometry will not be changed during the optimization, and all the optimization form will be connected to that preserve geometry. It should also be noted that the preserve geometry is where we'll define all our physics, the specific loads or constraints.
Selecting the preserve geometry, we can now go choose the specific connections. Immediately, they'll be represented as blue in the graphic screen. Optionally, you can choose to select and exclude geometry. In this case, we will. Now I can select the specific body that will represent the excluded geometry. As you can see under the exclude geometry, we have the keep out body defined, but it is actually hidden, so we'll actually turn on and show it on the screen. It'll be shown in red, representing again the exclude geometry. Normally I would define my loads, and in this case, I can choose my constraints or my loads, but I can also define specific load cases. In some cases of the optimization, you may have multiple load cases, and each can be defined independently.
Now that we have our design space and our physics defined, we can now go choose our design criteria. It is here that you're going to specify the specific design goals. We either have maximum stiffness or we have minimized mass, of which then we can choose the specific objective that we want to control. In this case, I want to maximize my stiffness by a targeted mass of 30%. We can also then specify specific design constraints. This is where we would define specific manufacturing constraints. If it's going to be additive manufacturing, if it's going to be milled, it's going to be cast, and so forth. In this case, I'll select it as free. I'm not going to choose a specific manufacturing constraint, but I will choose a geometry constraint of symmetry.
In this case, I'll choose the front datum plane as I want the optimization to be equal on both sides. At this point now, we can run the optimization. As the optimization is running, it's going through each of the iterative steps to get that refined model based upon the design criteria. Once the optimization is complete, it'll show as green on your screen, representing that it has successfully converged and given you an optimal result. We can easily go in to look at the simulation display results by looking at either the Von Mises stress, or we can choose displacement. Again, it'll represent on the screen what the specific displacement in this case is on the optimal results. If necessary, we can also run the animation and view how the model is going to deform.
If the optimized results meet our objectives, we can now perform the generative design reconstruction process. Clicking on the generative design icon, we can now choose to either output the result as tessellated that we could send directly to the 3D printer, or we can actually go create the reconstruction geometry, which will create that rich B-Rep geometry that we can use for downstream purposes. In this case, I'll choose reconstruction, and I'll choose level one for the level of resolution. Clicking on generate, it will now start the process of reconstructing the geometry for us. As you can see, the geometry successfully reconstructed, resulting in a rich B-Rep geometry model, which I can now use in downstream processes such as simulation or manufacturing. Within the model tree, we now see a generative design feature and then a group of features created from the reconstruction process.
Turning off the keep out area just to look at the specific results, we can now look at our model and clearly see how it was able to successfully reconstruct for our purposes. Going back into the generative design feature, we could take a look at some of the other design scenarios, the other design criteria. In this case, I have one for milling, for 3D printing, and for casting. Again, I could rerun the optimization for each one of those, yield a different result, reconstruct it for other downstream purposes. When we are within GTO, there will always be one result that can be processed at a time. Again, during the reconstruction process, I can output it as a new part. As I mentioned, there are two modules for generative design inside of Creo. The first, obviously, as I'm demonstrating, is GTO.
The other is generative design extension, the ability to upload to the cloud your complete study that will contain a variety of design criteria or scenarios with their own specific materials and so forth, and be able to run these simultaneously and be able to get all the results computed at once so that you can easily compare, filter, and find the solution that meets your needs. In this case, I'm going to click on send to cloud. Once you authenticate, you can now upload your geometry, your study directly to the cloud. We'll click on create. Now we can see all our design scenarios, the free design criteria, milling, 3D printing, etc. We could pick and choose specific ones we want to do and have them run simultaneously or simply select all and choose them to be all done at once.
This will consume, based on the GDX license, a certain number of credits that would be allotted for the optimization when you do select the specific items. At this point, we'll click on generate. This will start to optimize each of those specific scenarios with the different materials, etc., simultaneously. As they're computed, we can see the progress start in the viewing window on the screen. As they complete, we'll start to see them populate in the specific graphs. We can easily start to filter out and search by specific scenarios that meet our overall design objectives.
As the results are populated in the graph, we can also now start to filter whether it's by specific design criteria, the scenarios, or by the specific materials in question, or we can actually go and navigate on here within the linear graph where we can now start to search by specific objectives that we need to look at. As you can see, as I start to drag this menu around, it starts to highlight the specific items in the graph, in this case of max stress versus mass, that we can actually see the specific items in question. Now that we have our results generated, we want to start to compare a few of them together. In this case, I could go through and select specific ones that might meet my need. Maybe I want to look at safety factor, mass, and so forth.
We could go choose up to three. In this case, I'm going to choose a 3D printing, 3D printing, and a milling scenario. Now I'll select on compare. As soon as we do this, it's going to now show the results presented on the screen. At this point, we could then start to evaluate, look at them either in shaded mode if we want to look at the stresses, Von Mises stress, or even at the displacement. If there's a particular one that I'm interested in, I can now go and select send to Creo. This will open up the save a copy dialog inside of Creo where it'll give it its distinct name, and it'll download it from the cloud where I can now start to do the reconstruction. Now we have the downloaded part open up in Creo.
We can easily select on the generative design feature and perform the reconstruction. In this case, again, I'll do level one, and it'll start that process. Now that the reconstruction is finished, I can use this rich B-Rep geometry for my downstream processes. Hopefully, through this demonstration, you get a sense of how easy generative design is to use, certainly set up, run the optimization, and see it happen real time in front of your eyes, and then be able to go make modifications if necessary or continue through reconstruction to create that rich B-Rep geometry. Alternatively, if you have multiple design scenarios and you want to run them simultaneously, leveraging Generative Design Extension to upload your study to the cloud and quickly compare the results to find the result that best meets your need, bring it back into Creo, and then proceed with your design process.
Since the introduction in Creo 7.0, PTC continues to enhance the capabilities of generative design. Some enhancements come directly from feedback gathered from the user community, while others simply unlock the potential of the generative design solvers. The result is an unparalleled solution within Creo that aids in the user's design process. Let's review a number of the key enhancements introduced in each release of Creo since the introduction back in Creo 7.0. In Creo 8.0, generative topology optimization introduced support for Creo Process Manager and asynchronous processing. Users can start an optimization, have it tracked in the Process Manager while working on other models in their session. No longer do users need to wait for their optimization to finish before they can perform other tasks.
In addition, users can let Creo automatically create the starting geometry envelope without needing to create and define a body to be used as the starting geometry. Lastly, a new geometry constraint was introduced within the design criteria called minimum crease radius. This helps smoothen a user's generative results, maintaining curvature close to a minimum radius value. In Creo 9.0, generative topology optimization introduced support of a new design goal that minimizes the mass at a specified safety factor limit. This will allow users to generate low mass parts that can support the given loading conditions. In addition, users can generate modal design studies to optimize the design based on frequency response of the part. This is useful when users want to generate designs to eliminate the risk of failure due to the resonant frequencies that the part might encounter.
In Creo 10.0, generative topology optimization introduced the support for rotational symmetry. This new geometry constraint will allow users to choose the axis of rotation to be used in the optimization and define the number of instances to include in the rotational symmetry. In addition, generative topology optimization now supports the ability to define a force load through a point and apply it to preserve geometry surfaces in your study. This will represent a distributed load that is statistically equivalent to the load applied to the single remote point. Lastly, generative topology optimization now supports the ability to define a point mass idealization to the optimization setup. This will represent a concentrated mass without stiffness, requiring no additional geometry bodies, and the location of this point represents the center of gravity of that mass. Let's look at these Creo 10 enhancements in a live demonstration.
The first enhancement we're going to demonstrate is rotational symmetry. Selecting generative design through the applications tab, we can start this process. As you can see on the screen, I've already defined the specific design spaces, the starting geometry and the preserved geometry, as well as also applied my specific physics, the constraints and loads. Selecting the rotational symmetry design constraint, we could go edit this. The first thing that we want to do in defining rotational symmetry is click on the design constraints pull down menu and select symmetry. Now, symmetry is not new to Creo 10. We've had planar symmetry introduced since the introduction of generative topology optimization. What's new in Creo 10, though, is rotational symmetry. Within Creo 10.0, you have the option to do planar, you have the option to do rotational, or you have the option to do both together, both planar and rotational.
In this case, though, what I want to select is rotational. Now, as I mentioned earlier, you need to select specific options to define rotational symmetry. The first one is your axis of rotation. Let's go select the particular axis in question. Then we want to define the number of instances. The default is four, but in this case, I'll put six. If I didn't have a material defined, certainly I'd have to define that material. In this case, we'll click on okay, and now we can start the optimization. Now that the optimization is finished and converged on an optimal design, you can perform the reconstruction in order to create that rich B-Rep geometry for downstream use. This enhancement of rotational symmetry will allow you to ensure the optimal geometry is radially balanced.
It will enable you to explore alternative design solutions to improve control of geometry that is output from the generative design optimization. The second enhancement that we'll demonstrate is the ability to define a force load through a point and apply it to preserve geometry surfaces in our study. This will represent a distributed load that is statistically equivalent to the load applied to that single remote point. Selecting generative design under the applications tab, we can start this process. Like before, you could see that my design spaces have already been defined, my starting geometry and my preserved geometry. You'll notice that I have a defined constraint also applied, but I don't have any loads. This is where we're now going to apply that force point load.
Selecting the force from the pull down menu, we can now change the distributed type total force, which has historically been the default, to total load at point. Moving this down so I could see the point, I can now go and select this. Right now, the point that's selected is this PNT0. I also, though, need to select my specific references, which are corresponding to the preserved body surfaces. In this case, I'll choose the top surface. Now we can start to define the magnitude for which that force will be applied. In this case, I'll select directional component and apply a value in the negative y direction of 500 newtons. Now there's two behaviors that we can look at for total load at point. The default is deformable, but I have the choice to use rigid.
The deformable behavior will allow the connected bodies to deform but not add any stiffness to the system, whereas the rigid behavior will not allow the connected bodies to deform by adding stiffness. In this case, we'll keep the default of deformable. At this point, we can now start the optimization. Now that the optimization is finished and converged on an optimal shape, you'll notice that it's taken into account that force load through that point based on the design goals. Now we can easily perform reconstruction and create that rich B-Rep geometry for downstream use. This enhancement will allow you to easily apply a distributed force over selected references the load is applied to. You can now capture your design intent without compromising the loading conditions. Thank you for joining the session today, and I hope you have a clear understanding of these technologies inside of Creo.
More importantly, how these tools can help transform your design process, empower you to optimize your designs and drive innovation, make your work more impactful and valuable in today's dynamic market. Over to you, Jacqueline.
