[msh2vtu] fix for BHE meshes

Purpose

Modificaton for msh2vtu to allow to convert BHE meshes. For this it is needed to embed line elements in the 3D domain mesh. To do this msh2vtu has to be called with a list of dimensions: msh2vtu(..., dim=[1, 3], ...)

Also, added proper docstring to msh2vtu and mirrored it in the cli help API change:

• renamed rdcd to reindex
• renamed ogs to keep_ids with opposite meaning (keep_ids is False by defaulse which results in renaming gmsh:physical to MaterialIDs)

Categories

• preprocessing
