I cannot export a pentahedral element that resembles a pyramid shape
Hi everyone, I am a user from China, I want to divide a pyramid-like pentahedral mesh while using Gmsh, but my mesh has this pentahedral cell explicitly in it, but the output .inp file is missing this pyramid cell, what is the problem, or is there another way to divide a pyramid-shaped pentahedral mesh and export the .inp file? Is there another way to divide the pyramidal mesh and export it in .inp format? I would appreciate your answer. Here are my modelling file (.geo) and the output file (.inp).
