Generating volume mesh from a given surface mesh
I would like to have an accurate mesh of a printed circuit board (PCB), which provides a converged field simulation result. The PCB consists of the metallic objects (cylindrical vias, thin lines and planes) and the background material (dielectric). Unfortunately, the regions of the vias and the thin lines require a high number of mesh cells, which is not known in advance. The external field simulation software CST Microwave Studio, which serves as reference for our simulation, provides the oppurtunity to export the (accurate) surface mesh of the metallic objects as STL-file. The entire volume mesh cannot be exported. Is there the possibility to import the STL-file in Gmsh, which can be used for a volume mesh generation in Gmsh? I would be very pleased about a response and thank you in advance.
With kind regards Sebastian Südekum
