Gridgen Gridgen is the premiere commercial grid generation suite from Pointwise Inc and has been widely used by engineers since 1984. Gridgen generates structured hex, unstructured tet, and hybrid meshes. A wide variety of native CAD readers are available including CATIA, Pro/Engineer, STEP, Unigraphics (Siemans PLM). In addition Gridgen supports the CADNexus Capri CAE Gateway that works directly with a CAD systems kernel. Gridgen also supports standard formats such as PLOT3D, STL triangular faceted data, and IGES. Gridgen includes several diagnostic tools to ensure mesh quality. Cell-to-cell size variation, aspect ratio, Jacobian, skewness, smoothness can all be visualized to ensure adequate grid quality.
Pointwise Pointwise is the most recent addition to Pointwise Inc's grid generation suite. Pointwise features an updated interface with advanced automation to ease the grid generation process. Most of the features of Gridgen are available in Pointwise. Pointwise supports both structured and unstructured mesh generation and supports IGES, PATRAN, STL, VRML, NASTRAN and PLOT3D geometries. Pointwise includes twenty-five mesh quality metrics which can be displayed during the grid generation process.
SolidMesh SolidMesh is an unstructured grid generation system developed by the ERC Computational Simulation and Design Center at Mississippi State University. SolidMesh allows the user to quickly generate high quality three dimensional unstructured meshes about complex geometries. Geometries can be imported into SolidMesh in a variety of native CAD formats and supports the CADNexus Capri CAE gateway in addition to the standard IGES, STL, and PLOT3D formats.
VGRIDns VGRIDns is an unstructured grid generation application which is part of the TetrUSS CFD suite available from NASA Langley. VGRIDns generates homogeneous unstructured tetrahedral meshes for Euler and Navier-Stokes simulations. VGRIDns is well known for it's ability to generate viscous layer meshes with tetrahedral elements instead of using the hybrid approach where prisms are generated off the surface and transition into tetrahedral outside the viscous layer. The TetrUSS software suite is well tested and used widely by NASA and industry.
