Hi to all,
I want to read a mesh from a tetgen-output file. In tetgen I have
specified different regions. Now I am trying to read the mesh by:
Mesh new_mesh;
new_mesh.read("mesh/almirante_box.1.ele");
Here are the first lines of my *.ele file:
542385 4 1
1 16340 63454 13659 86041 1
2 44851 69045 38700 85823 1
3 39598 38395 28168 28167 1
4 54393 80195 67081 80196 2
5 15767 74613 35521 53993 2
6 11944 83706 12467 87606 1
7 5102 6153 7395 16715 2
8 75849 79502 33646 79520 1
9 10026 61126 14569 71718 1
10 50667 50803 33989 79888 1
As you can see, the last figures describe to which region the respective
tetrahedra belongs. However, now I am stuck with the quite simple
problem to find these values in my libmesh-mesh.
I have tried something like:
elem->subdomain_id();
when looping through the elements. But since the new_mesh.n_subdomains()
returns 1, this didn't work.
Thank you for your help,
Robert
