Iterative change of geometry in CAD and exporting it in Workbench

[SuG89]

Hello,

I am using Rhinoceros (CAD) and Ansys Workbench (FEA). Basically exporting solid models from CAD to FEA. In FEA, the procedure followed is:

1. Giving meaningful names to different geometry components
2. Assigning material
3. Defining contacts
4. Meshing
5. Setting up loads and boundary conditions
6. Setting up analysis properties - large deformation, etc.

Now after the first FEA run if I change something in a geometry component in CAD (example: fillet the sharp edges, increase bolt and hole diameter, etc.) then I have to import the new file in FEA. This leads to repetition of step 1-6. Is there a way to be able to make small geometry changes without repeating all the steps (especially 1 and 3)?

Regards,
Sushant

Why are you not using design modeller of workbench? If you can use design modeller then at the CAD model itself you can set the parameters which you want to change in the subsequent iterations and make your life simpler.

Step 1 and 3 anyway you need to redo. But Ansys own parametric modelling and parametric analysis setup setting with will make it easy for iterations.

If you have access to Spaceclaim, it could be easier to use than Design modeller. Spaceclaim models can also be parametrized to some extent.

Hi, Thanks for your answers.

I don't have access to SpaceClaim. I have tried using the Design Modeller but it is not as user-friendly as Rhinoceros or AutoCAD. Still I'll try to get deeper into DM.
