Hi all;

I try to import a STL file to Comsol 4.3a but this error appeared "Face Cannot be parameterized"?

Any help?

Thanks in advance :)

Hi

from my experience, not much to do as STL is not a "solid" 3D format, if you could use STEP, ACIS or Parasolid or one of the native 3D geometry formats you will have more chances to get the import successful

Good luck

Hi!
I managed to find a solution. It is not trivial nor free. We can import the .stl file with +CAD (Simpleware), convert it to a mask and then save/export it as a +ScanIP (simpleware) file. Once in +ScanIP we open the file with the mask and we create a NURBS surface from the mask. We can export the mesh in different formats that comsol accepts. I tried with .igs extension and it worked.

I followed a suggestion here

Hope it helps someone.
