💥💥💥 How to simplify model in Ansys Design Modeler?

 Simplifying a model in Ansys Design Modeler can help you to obtain a better mesh quality, reduce the simulation run time and improve the accuracy of the results. There are different ways to simplify a model depending on the type and complexity of the geometry. Here are some general steps that you can follow:

- Remove unnecessary features such as fillets, rounds, small holes, etc. that do not affect the global behavior of the model. You can use the fill command in Ansys SpaceClaim or the Simplify Geometry option in DesignModeler to do this¹².

- Replace insignificant bodies or parts with simplified geometries or constraints. For example, you can replace bolts with beam elements or rigid contacts, or you can remove screws and nuts and apply fixed boundary conditions instead².

- Convert the bodies that you want to export to DesignModeler type by using the conversion operation or the Simplify Topology option in DesignModeler. This will ensure that all the bodies are exported successfully to the required neutral file format³.

How to simplify complex multibody geometry in Ansys Design Modeler for Fluent?

Simplifying complex multibody geometry in Ansys Design Modeler for Fluent can be challenging, but not impossible. There are some tips and tricks that you can use to reduce the complexity of your geometry and make it more suitable for meshing and solving in Fluent. Here are some of them:

- Use the Simplify Geometry option in DesignModeler to automatically remove unnecessary features such as fillets, rounds, small holes, etc. that do not affect the global behavior of the model. You can access this option by right-clicking on the Geometry tab in Workbench and selecting Edit in DesignModeler. Then, make sure the Simplify Geometry and Simplify Topology options are set to Yes in the Details view of the geometry. You can also adjust the tolerance and the maximum feature size parameters to control the level of simplification¹.

- Use the Fill command in Ansys SpaceClaim to manually delete unwanted features or fill gaps in your geometry. You can access this command by right-clicking on the Geometry tab in Workbench and selecting Edit in SpaceClaim. Then, select the faces or edges that you want to remove or fill and click on the Fill icon in the Design tab. You can also use the Pull command to modify the geometry by dragging, offsetting, or extruding the selected faces or edges².

- Use the Conversion operation in DesignModeler to convert the bodies that you want to export to DesignModeler type. This will ensure that all the bodies are exported successfully to the required neutral file format. You can access this operation by selecting the bodies in the Tree Outline and clicking on the Conversion icon in the Operation toolbar. You can also use the Simplify Topology option in DesignModeler to convert the bodies to the simplest possible topology³.

- Use the Sew operation in DesignModeler to connect bodies with different topologies or gaps between them. This will create a single solid body that can be meshed and solved in Fluent. You can access this operation by selecting the bodies in the Tree Outline and clicking on the Sew icon in the Operation toolbar. You can also use the Create operation to create lines and surfaces between the bodies and then sew them together.

Can I simplify my mesh instead of geometry?

Yes, you can simplify your mesh instead of geometry, but it depends on the type and quality of the mesh that you want to use for your analysis. Generally, there are two types of meshes that you can use in FEA: hexahedral (brick) meshes and tetrahedral (tet) meshes. Hex meshes are more accurate and efficient, but they require more geometry preparation and are not suitable for complex shapes. Tet meshes are more flexible and can handle any geometry, but they are less accurate and require more elements and higher order elements to achieve the same accuracy as hex meshes³.

To simplify your mesh, you can use different meshing methods and parameters in Ansys DesignModeler or Ansys Mechanical. For example, you can use the Multizone method, which is a hybrid of hex and tet elements that allows you to mesh different parts of the geometry with different methods. This allows you to perform less geometry preparation and have more local control over the meshes³. You can also use the Meshing Toolbox in Ansys Mechanical to refine, smooth, or inflate your mesh according to your needs.

However, simplifying your mesh alone may not be enough to improve your FEA model. You should also consider the boundary conditions, the material properties, and the physics of the problem that you are trying to solve. Simplifying your mesh may reduce the computational cost and time, but it may also introduce errors or inaccuracies in your results. Therefore, you should always check the quality of your mesh and verify your results with analytical solutions or experimental data. You can find more information and examples on how to simplify your mesh in Ansys DesignModeler or Ansys Mechanical by following the links in the web search results. I hope this helps you to improve your FEA model. 😊.

Can I use other software for simplify geometry instead of Ansys Design Modeler or SpaceClaim ?

Yes, you can use other software for simplifying geometry instead of Ansys Design Modeler or SpaceClaim, as long as they are compatible with the file formats that Ansys supports. For example, you can use Geometry Calculator¹ or Desmos² to create and simplify 2D geometries, or you can use Geoprocessing Online³ or CoreTechnologie⁴ to simplify 3D geometries. However, you should be aware that different software may have different algorithms and parameters for simplifying geometry, and they may not preserve the topology or the accuracy of the original geometry. Therefore, you should always check the quality of the simplified geometry and compare it with the original geometry before importing it to Ansys. You can find more information and examples on how to use other software for simplifying geometry by following the links in the web search results. I hope this helps you to improve your FEA model. 😊.

What is better: Ansys SpaceClaim or Ansys Design Modeler?

There is no definitive answer to which tool is better, as it may depend on your preferences, needs, and use cases. However, I can provide you with some information and comparisons based on the web search results that I have found.

- ANSYS DesignModeler (DM) and ANSYS Discovery SpaceClaim (SC) are both 3D modeling tools that can be used for creating and modifying geometry for simulation purposes¹.

- DM and SC use different geometry modeling kernels: DM uses Parasolid, while SC uses ACIS². This means that moving data between DM and other tools that use Parasolid (such as SOLIDWORKS) is easier than moving data between SC and those tools, as there is no need for translation². However, SC can also import and export various file formats, such as STEP, IGES, STL, etc³.

- DM has a history tree that records the sequence of operations performed on the geometry, while SC does not have a history tree by default (although it can be enabled with an optional feature)². This means that DM allows you to easily modify the parameters and constraints of the geometry at any stage, while SC requires you to use the block recording function to save and replay the operations⁴.

- SC has a more intuitive and user-friendly interface than DM, as it uses direct modeling techniques that allow you to manipulate the geometry with simple gestures such as drag, pull, move, etc³. SC also has more advanced features such as repair, simplify, optimize, etc., that can help you prepare the geometry for simulation faster and easier³.

- Both DM and SC have their own advantages and disadvantages, and you may need to use both of them depending on the situation. For example, you may want to use DM for parametric design and optimization, and use SC for complex geometry creation and modification².
