A Procedure for Generating Well Conditioned Tetrahedral Meshes
On the premise that tetrahedra (particularly ten noded ones) make good finite elements and that they should be as near regular as possible a procedure for generating structured meshes of such elements is outlined. This involves two stages: First the definition, by means of macro elements, of a regular array of optimally shaped and suitably sized tetrahedra which fill the region. Then the distortion of the mesh thus obtained to better fit the boundaries. Examples are given which demonstrate the suitability of the procedure for, in particular, static analyses in geomechanics.
