Exporting to Gambit neutral file format (.neu): writing boundaries
When meshing this file tpv33_half.geo using:
gmsh tpv33_half.geo -3 -optimize -format msh22 [Gmsh 4.3.0-git-5520d784, 1 node, max. 1 thread]
I got a correct number of boundary elements, that is 1714 elements for surface 105 for example. (I guess it is not straightforward to see in the msh format. I use gmsh2gambit to convert the msh to neu file and to read the boundary conditions).
BOUNDARY CONDITIONS 2.0.0 105 1 1714 0 6
On the other hand, when I try to directly export to neu file with:
gmsh tpv33_half.geo -3 -optimize -format neu
I only get 1624 elements for surface 105. This means there is a problem in exporting boundaries to Gambit neutral format.
