[Gmsh] STL remeshing and mesh refinement at defined points in gmsh

[Eligiusz Postek]

Hi, I do sometimes
such a thing like this:
1) I create a "skin" - with finite elements
2) I convert the triangles into the geometry
3) I convert a volume mesh

An examples is in the attachement,
best regards
Elek
