ANSYS ICEM CFD: Hex and Tet Element Specification

May 24, 2006, 16:36

How do you specify whether linear or quadratic basis functions are used? I'd like to use Hexa_20 and Tetra_10 elements instead of their linear basis counterparts Hexa_8 and Tetra_4, but am unable to find a setting that lets you specify the element type.

I'm just creating an unstructured mesh using the automeshers, and am using LS-DYNA as the solver.

Any help with this would be greatly appreciated! Evan

After creation of linear elements just choose Edit Mesh->Create Mid Side Nodes (button #2 on this toolbar). This will give you just what you want.
