ElmerGrid does not correctly write the boundary names when transforming UNV files from salome. I haven't checked the code but I suspect that this commit is the problem https://github.com/ElmerCSC/elmerfem/co ... a1e35ad7b8. Is there a flag to have this problem fixed or is this an unintended consequence of the experimental code introduced in this commit?
I'll second that observation. I saw it with unv files generated by FreeCAD. I tested an installer dated 21 Sep 2022, which is prior to the referenced commit, and the earlier version works properly.
As a follow up, after testing with the windows installer dated 12 Nov 2022, elmergrid properly creates the mesh.names file while converting the Freecad generated unv file.
I am still having issues with some mesh files (unv form salome). For instance, if I don't group some lines/surfaces in the mesh and then convert them with ElmerGrid, these ungrouped geometries are incorrectly labelled. In previous versions all these geometries were lumped together into a bnryX where X was a number. Now, if the ungrouped geometry is a surface, they are assigned a random name, but if the ungrouped geometries are a line, their name is empty.
