I wonder how to generate tetrahedra meshes, necessary for Brillouin zone integration. I prefer very simple one based on Lehmann and Taut (1972). Is there any algorithm to generate meshes by giving crystal symmetry, lattice constants, and number of desired tetrahedra etc? I think the algorithm for integration will depend on the quantity that one wants to evaluate. So, only mesh generation part would be sufficient for me.

You can use GAMBIT software for mesh genaration.
What is the function of mesh generation for you. For example do you want FEM/CFD/FSI simulation? IF yes you can use ANSYS/ABAQUS/ADINA software
Thanks very much. Dr. Seifollah. I wish simply know the coordinates of position if I truncate a cube into six tetrahedra. The desired one corresponds to (e) of the following link.: http://www.iue.tuwien.ac.at/phd/wessner/img470.png
