WebAug 22, 2024 · According to GMSH philosophy, and this job is best left to the solver, GMSH provides a simple mechanism to tag groups of elements – which you are already using. The long version: I guess, the intention is to use *.msh file (obtained by GMSH processing the corresponding *.geo file) as an input to the FEM solver. WebJan 30, 2024 · No, I don't think your tip will work. Look at _write_elements(), fcd is an empty array, meshio currently does not dump the the physical and elementary tags.
