Hello, I am trying to mesh a volume enclosed by two surface groups consisting of an STL mesh and a surface defined using elementary entities. An example is a box sketched as the below:
The top in red is an STL or NAS mesh surface, the bottom and sides are built using points, lines and surface loops. ______ |______| After the bottom is meshed, I am able to obtain edge nodes that match the edge nodes of the STL surface perfectly. Hence at the seam of the red and black surfaces there are duplicated nodes. Because of these, during the volume meshing GMSH/Tetgen rightfully complains about self intersections. Can I somehow force GMSH to paste the duplicated nodes across the STL facets and the elementary surface facets before volume meshing? If I need to edit the code for this, what data would you recommend me to modify? Thank you for your help. Best, -- Cem Albukrek, Ph.D. Senior Aerodynamics Consultant, Tel: (857) 234-1035
