Trying to import Topology optimization results into inspire studio but tells me there is no mesh found

Rodrigo Padilla_21991

Hi, im trying to use the inspire studio Polynurbs tool to generate a CAD for 3D printing from a topology optimization result, I can´t import the STL file into the software since the geometry appears but when I try to use the wrap tool it tells me there is no valid tetra mesh, as shown on the picture. How can I export the result from optistruct to do this?

Hi @Rodrigo Padilla 

 

If you have Inspire (not IStudio), from 2020 or above, you can do this pretty easily.

1) import your .fem file into Inspire.

2) Select your desired parts, and use the 'Shrink Wrap' tool, under PolyMesh >> this will create a outer surface around your elements

3) then go to geometry, and use the 'Fit' tool inside PolyNURBS

4) export to your prefered format

Icons are in Portuguese, but you will find them easily.

 

The image below shows each step, from mesh (top right), to wrapped mesh (bottom) and polynurbs fitted (top right).
