ANSYS ICEM CFD offers several Tetra Meshing Schemes.
For our Patch independent OCTREE mesher, The user simply selects the CAD geometry (surfaces, curves and points) that describe the space to be meshed and ANSYS ICEM CFD Tetra automatically generates a triangular surface mesh and the interior tetrahedral mesh. Maximum element sizes can be defined on the surfaces and in volumes to reflect areas with a high gradient in the flow field. ICEM CFD Tetra automatically meshes the volume by successive refinement until all grid density requirements are met. The resulting tetrahedral mesh is an adaptive mesh of non-uniform density and it is independent of the CAD patch structure.

This Tetra model of a Race Car illustrates out the OCTREE tetra algorithm captures complex details. It also features curvature and proximity based refinement. |
 |
This external aero example shows how octree tetra easily walks over the individual surface details to give a smooth mesh free of slivers, etc. |
ICEM CFD Tetra can automatically arrange layers of prism elements near the boundary surfaces in order to appropriately model close to wall physics. As a result, ICEM CFD Tetra automatically generates a hybrid tetrahedral grid consisting of prism elements near the boundary surfaces and tetrahedral elements in the interior of the space to be meshed. The thickness of the prism layers can be controlled by exponential or geometric growth laws.
ANSYS ICEM CFD Tetra also has the ability to turn TET cells into HEX cells! For more detailed information on this please click here.
