Coupling parametric CAD body with meshing and analysis setup in HyperMesh?

Hello everyone,

 

in order to perform a design exploration study of a compliant mechanism, I want to couple a parametric CAD part (.step for example) with HyperStudy and/or OptiStruct/Radioss in order to find optimal dimensions and thicknesses. It will be a revolved shape meshed with 2D elements. I found the tutorials for Simlab showing that it's possible to do in Simlab, but can it be done in HyperMesh as well? Ideally, the surfaces would be meshed by a constant number of quad elements along all edges to ensure sufficient accuracy at curves.

    There are a few tools in HM that could give you some access to changing the CAD, sch as the 'dimensioning' panel.

    But you would need to create scripts for calling HM and promoting these changes in your geoemtry and build the mesh and setup, which is not so trivial.

     

    As mentioned by you, But i would rather go to SimLab, as it has really easy Scripting tools (record and play) and it already has direct coupling with different CADs and HyperStudy. In SL learnng center there are a few tutorials about it.

    Simlab seems to be the weapon of choice, then. Another question concerning Simlab, can a fixed number of nodes be defined on an edge when performing automatic meshing of a parametric CAD body? This way, the mesh would always be consistent across variants. Thanks for your input.

    yes. You can control edge seed count.

    you may take a look at SL Learning Center, in the SL community.

    Thanks for your help, I'll definitely delve into Simlab.
