How to refine a generated mesh from a surface,

Hello,

is it possible to use Parameters to refine a generated Mesh with BRepMesh_Mesh or _IncrementalMesh? I have generated a mesh, and know I just only want to refine a domain of my mesh, because the geometry has to be more complex. I need this mesh as input for an FEM-Calcuation.

I hope someone can help.

AFAIK, BRepMesh is not what you are looking for. Although you can refine the mesh on a particular cascade face, the edge vertices will no longer line up with adjacent faces. In addition, BRepMesh tends to create meshes that do not work well with FEM calculations (long, skinny triangles). You might want to take a look at NETGEN (www.hpfem.jku.at/netgen/) or one of the other FEM mesh generators out there.
