CFD Meshing Software uses automated unstructured technique.
Press Release Summary:
Gridgen v15.10 features anisotropic tetrahedral meshing technique used for generating high-quality unstructured meshes for viscous CFD analysis. While automated technique generates layers of tetrahedra around complex geometries, program lets users locally adjust extrusion to improve cell quality and prevent collisions with adjacent extrusion fronts. Software also provides native interface to Tecplot visualization software as well as to CAD data via CADNexus' CAPRI software.
Original Press Release:
Automated Unstructured Viscous Meshing Featured in Gridgen V15.10
Fort Worth, Texas, 30 March 2007 - Pointwise announces the release of Gridgen Version 15.10, the latest version of their popular CFD meshing software. The major new feature in Gridgen V15.10 is a novel technique for generating high-quality unstructured meshes for viscous CFD analysis called anisotropic tetrahedral meshing.
"Anisotropic tetrahedral meshing is a truly unstructured extrusion process," said John Steinbrenner, Pointwise's Vice President of Research and Development. "Because it is unstructured, we can locally adjust the extrusion to improve cell quality and prevent collisions with adjacent extrusion fronts. This is very useful for those complex geometry cases where traditional prism extrusion fails: sharp corners, closely-spaced adjacent parts, and concave regions. The end result is our users will be able to create high quality CFD meshes more quickly than using other methods."
Gridgen's new anisotropic tetrahedral meshing is a highly automated technique for generating layers of high quality tetrahedra around complex geometries. Its advantages over traditional prism extrusion techniques are:
· it can extrude out of convex regions,
· it automatically detects and avoids collisions with other extrusions,
· it can stop locally in regions where cell quality criteria are not being met, and
· it can handle high aspect ratio tetrahedral cells.
Together these improvements in Gridgen mean users are able to finish the meshing task more quickly and reliably for today's large, high-fidelity, 3D models.
Other significant new features in Gridgen Version 15.10 include a native interface to the Tecplot visualization software and an interface to CAD data via CADNexus' CAPRI software.
