Mesh Format 2.2
Dear all.
I am stuck in the gmsh 2.2 format for a 2D mesh. When I use t1.geo file from the tutorial, adding the following lines
Mesh.MshFileVersion = 2.2;
Mesh.PartitionOldStyleMsh2 = 1;
Mesh.PartitionCreateGhostCells = 1;
and save the file in ASCII, I am not able to find where it is written the following line:
Physical Curve(5) = {1, 2, 4};
In the $Elements section, there are two tags that there should be the physical entity and the geometrical entity number, so for all the edges in the geometrical entities 1, 2 and 4 I would expect to have the two tags 5 1, 5 2 or 5 4, whereas I get something like
...
52 1 2 0 3 49 50
53 1 2 0 3 50 51
54 1 2 0 3 51 4
55 1 2 0 4 4 52
56 1 2 0 4 52 53
57 1 2 0 4 53 54
58 1 2 0 4 54 55
...
If I understood properly the manual, the numbers corresponds to elm-number elm-type number-of-tags physical-entity geometrical-entity node1 node2
How do I know from the mesh file that those edges are grouped in the same physical entity?
Best regards.
