[Gmsh] Importing an IGES File

[Alex Evanovic]

Hi,

I have a problem while importing an IGES file into gmsh. The geometry gets
imported but the meshing does not get imported.

When I import it to gmsh, I get the geometry, but not the meshing in the
IGES file. I have to mesh it in gmsh again which I do not prefer. I want the
IGES meshing retained.

Please note that my gmsh version is compiled with Open Cascade. It's the dev
version, gmsh nightly windows version.

Could someone please suggest regarding this?

Regards,
Alex

I didn't know the IGES file format supported meshing. Are you sure it
does? There's no mention of it at http://ts.nist.gov/standards/iges,
for example. Perhaps when you generated the geometry and mesh
(howsoever, wheresoever) and saved it as IGES, only the geometrical
information was stored?

Hi Geordie,

Yes, you are right. IGES does not support gmsh. I exported it as a .unv file
and that worked.

Thanks,
Alex
