Dear sir! My name is Denis Martynov, I'm a student of Moscow Institute of Physics and Technology, department of general and applied physics. My science team needs tetrahedral meshes in physical space for solving our tasks. At this stage I build mesh using GMSH, then save it using binary .msh format, and then load this file to my C++ program. Now I have to find out for each tetrahedron its neighbours myself and this takes some time...I wonder if GMSH can type a list of neighbors for each tetrahedron? I use Delaynay algorithm that is optimized by Netgen. And I have another question. It is actual if GMSH can't type neighbors of each tetrahedron. This is about ruled surfaces. In GMSH tutorial one can read about ruled surface: "a surface that can be interpolated using transfinite interpolation". How can I get the equation of the surface to define which tetrahedrons border this surface? Sincerely, Denis Martynov.
