Hi, everybody.


I have a problem trying to export a mesh 2D from NGSolve to Elmer (CFD software).
At the beginning I tried to open the geometry (step file) with Elmer to generate the mesh. However, it has problems to import 2D geometries and the mesh is generated with defects. Then, I tried with Ngsolve which could open the stp file and generate a good mesh, but now I can't export the file to one format to work with Elmer. Ngsolve doesn't export to Elmer format. I tried to export with the inp format of Abaqus, but the software crush.
I tried to export into a msh format but Elmer fail to open it.
Some suggestion?

If you have access to ANSYS (at least older versions running APDL), there are Elmer Macros to directly export the mesh to ELMER.

Thanks. Finally, I make the geometry in iges format, then I export the mesh in msh format from NGSolve and with Elmer I can open it without problem.

thanks.
