hexahedral mesh over a 3D prism meshed with quadrilaterals
Hello, I am happy to be able to ask my question on Gmsh here. I have a prism-like volume with rectangular ends and want to mesh it with 3D elements. the whole six surfaces of the prism are meshed using "Recombine" method and are quadrilateral. However, in 3D mesh, a "tetrahedrazing" occurs and the result is not quadrilateral. How can I keep it like structured hexahedral mesh in 3D. Please see the attached script and I hope I was able to make my question clearly.NP1.geo
