I have a question about how we can get the physical surface No. for
elements in GMSH File.
In default format of tetrahedorn Triangle mesh data as follow
117 2 3 0 1000028 0 436 359 371
3: number of tags
0: The first tag is the number of the physaical entity to which the element
0: The third tag is the number of the mesh partition to which the element
What reason does all entities of the first tag was show 0 for any Triangle
elements (ie. Elm-type 2)?
I wish to output the right first tag (the 3D element number with the 2D
Triangle of the Elm-type 2).
In addition, the 3D element number may be using the total Elm-number, or the
order for list of 3D element by itself.
