Happy new year.
I have question (may be unstability) about
.prj file, when I studied the 3D example link.
This example shows that in the case of mixed 2D and 3D mesh. Using ‘msh2vtu.py’, the
MaterialIDs can be degined for both the 2D physical groups (planes) and the 3D physical groups (the bulk domain).
However, when I tried another example, typically the tutorial example of Gmsh link of t15.geo, it did not work.
In that case, I can not get
MaterialIDs for all physical groups (I only got the
MaterialIDs of bulk, the embedded plane and lines were failed to get
MaterialIDs). I do not why.
Could you give me some hints?
