You should set the manifold ids of the two regions to different numbers, and add the second manifold with the second id you choose, otherwise the second call is simply overwriting the first one, and they are both described by the last manifold. LucaIl giorno 20 feb 2023, alle ore 07:08, Deepika Ku
I have meshed my cad model in gmesh and provided bounday ids for different
surfaces by add physical group option and saved mesh in .msh file format.
the first few lines of .msh file look like this:
$MeshFormat
2.2 0 8
$EndMeshFormat
$PhysicalNames

2 14 "top"
2 15 "inner"

Greg,
By two meshes matching do you mean there is no hanging nodes? Or they come
from the same Triangulation object (and same DoFHandler object, for that matter)?
I meant that a face of the triangulation used for the "old" slab exactly
matches a face of the triangulation used for the "new"
