Dear group, dear devs,

I am using the method "bempp.api.grid_from_element_data" to create grids with material assined and then export them in the gmsh format. It seems that the domain_indices are being ignored when exporting the mesh as .msh file.

Please see the attached snippet of code for illustration. It shows that the "domain_indices" are not correct after exporting and re-importing the grid. Might there be a bug in the export routine or is that the expeced behavior? The domain_indices are meant to relate to the 'Physical groups' in GMSH, did I get that right?

Best regards,

Martin

Dear Martin,

thanks for making me aware of this. We won't fix in in Bempp 3.3 any more. But I will include the fix in the next version.

Best wishes

Timo
