Hello all,
I need pure hexahedral mesh for complex geometries of human body parts such as human skull, femur, shoulder etc. I have made an attempt with ANSYS ICEM and IA-FEMesh softwares using multi-blocking techniques, but I am unable to produce Hex mesh. I am attaching snaps of geometries alongwith.
Can anyone have an idea how to generate such mesh on complex geometries?

If your parts are like the one in your image, you simply can't. There is this theorem using Euler's characteristic which says that a polyhedron with the topology of a sphere that is composed with hexagons or pentagons should always have 12 pentagons. Actually you need to have something isomorphic to a torus.
