Hexahedral mesh with CFX-Mesh
Hi, everybody

I need to mesh a geometry with hexahedral elements. Can I do it in CFX-Mesh? I only can do it with triangles and quads.

Re: Hexahedral mesh with CFX-Mesh
In CFX-Mesh, you can technically create a structured mesh by extruding one face (i.e. surface mesh) out across the entire domain. This means for simple geometries such as a straight pipe, it can be done. For any more complicated geometries you will have trouble extruding the mesh properly and it will either fail or generate a poor mesh. See the documentation for info on extruding, or look into gridgen or another meshing package to generate more complex structured meshes.

Why look for gridgen if ANSYS ICEM CFD is superior? And better suited to CFX...

Re: Hexahedral mesh.I don’t know if it is possib
Thanks for your advice

As you have said, I have created a structured mesh by extruding one face (extruding 2D mesh with option n of layers = 1) but the problem is that I have what I want in only one direction. If I try to use inflation and extruding together, I only have a hexahedral mesh near the walls, not in all the geometry. Why? Is there any option to apply inflation to all the geometry?

Regards, Isabel
