Pointwise Offers Advanced Hybrid Meshing for CFD in Gridgen

By DE Editors

Pointwise (Fort Worth, TX) announced the latest release of its Gridgen meshing software with enhanced hybrid mesh generation capabilities for computational fluid dynamics (CFD).

Gridgen’s most advanced hybrid meshing technique is anisotropic tetrahedral extrusion where layers of high-quality, high-aspect ratio tetrahedra are extruded from a triangular surface mesh in order to resolve boundary layers and other near-wall phenomena.

The new Gridgen speeds up the extrusion process by a factor of up to 10, says the company, and expands the capability of anisotropic triangle generation for highly curved surfaces. Plus, it improves the robustness of the tetrahedral mesh generator when surface edge lengths vary more than 6 orders of magnitude.

In addition to the hybrid meshing improvements, new capabilities in Gridgen Version 15.12 include a mesh quality metric for the ratio of adjacent cell volumes, face-based CGNS export, and the ability to import CATIA V5 R18 and NX 5 CAD format files.

Pointwise also announced that Jon Beesley, Director and Chief Test Pilot at Lockheed Martin Aeronautics, will deliver the keynote address at the Pointwise User Group Meeting 2008 in November 2008. He is the recipient of numerous awards.
