[Gmsh] Question on gmsh meshing with size determined by executable

[moritz braun]

Dear Christophe

I am currently using gmsh  with a size function
that becomes very small, but not zero
close to the positions of nuclei in a molecule
and is scaling close to linear for distances > 0.1 abohr.
More specifically
i have chosen the size function as
S*sqrt(0.02**2+d**2), with S as a parameter between 0.1 and 0.5
It would possbily make my calculation more exact
if I could force gmsh to use the nuclear positions
as grid points.
Is there a way to  get gmsh to do that?

Regards

Moritz
