Hi, I'm using the finite element library deal.II to generate some '.msh' files, and exporting through deal.II. I find that all I can export is the mesh itself, with no boundaries define.d
I would like to modify the meshes by adding in boundary conditions through using physical entities in gmsh, since I want to import these meshes into OpenFOAM for later manipulation. However, I can't actually find any way to do this. Is it possible to do this in gmsh somehow? I find that all I can do is add a 'volume' physical entity which takes up the entire volume. The .msh basically looks like: $MeshFormat 2.2 0 8 $EndMeshFormat $Nodes 429 1 0 0.333333 0.333333 2 0.333333 0.333333 0.333333 . . . 428 0.416667 0.583333 0.75 429 0.583333 0.583333 0.75 $EndNodes $Elements 248 1 5 2 2 1 13 107 197 63 110 304 310 199 . . . 248 5 2 2 1 392 100 260 429 349 11 105 393 $EndElements Sincerely, James Xie
