construct explicit tetra

[alessiofumagalli]

Dear all,

in a 3d geometry, is it possible to construct by hand some of tetrahedra and let gmsh build the others, obtaining a conforming mesh? I'm using the python api.
Thanks a lot for your kind help,

Alessio

Not with Gmsh, I don't think.

I was using the gmsh.model.mesh.addElementsByType and get some results, but I have troubles making the generated grid conforming with the given tetra

another possibility is to prevent gmsh to add new point on a given surface, with this I might be able to fix my issue
