[Gmsh] How to include specific nodes in tetrahedral mesh

[moritz braun]

Dear  Friends
Dear Christophe

For some planned research I have two questions
1.How can include specific  points as part of the final refined
tetrahedral mesh, since
they are the points at which the coulomb potential has a singularity
and any numerical integration
will only be possible if the nucleus is chosen as node of the tetrahedron?
2. How can I supply ad-hoc  integration grids and weights for
those  tetrahedron that require special ones

regards

Moritz
