BEDFORD, TX (1 October 1995) – Pointwise today announced the release of Gridgen Version 10.8, the latest revision of its grid generation software product. Included in v10.8 are a direct interface to AeroSoft, Inc.'s GASP computational fluid dynamics (CFD) software and a geometry modeler with the correct combination of capabilities for making computer aided design (CAD) models analysis ready.
"Attendees at May's NASA conference on grid generation acknowledged that the greatest barrier to efficient mesh generation is the capture and utilization of geometry models from CAD systems," said John Chawner, Pointwise's president. "Gridgen Version 10.8 breaks through that barrier by providing tools that enable the user to repair and supplement CAD models allowing them to be gridded." Grid generators also suffer from a post-processing dilemma: formatting the grid data for their particular CFD software. Gridgen's interface to GASP furthers Pointwise's goal of working with leading analysis vendors in order to provide its users with the most complete grid generation and preprocessing software.
Gridgen's new geometry modeling capability includes: an interactive intersection routine including curve - curve, curve - plane, curve - surface, surface - plane, and surface - surface intersections; linear, cylindrical, spherical, and closest point projections; point, average point, line, curve, circle, conic, offset curve, ruled surface, surface of revolution, and polyconic surface creation capabilities.
GASP solves the steady and unsteady, 3D, Reynolds averaged, Navier Stokes equations using a fully conservative, cell centered, upwind, finite difference numerical algorithm including finite-rate, frozen, and equilibrium chemistry. Unique among commercial CFD codes, GASP users are provided with 100% of the program's source code.
Gridgen is used by engineers and scientists in the preparation of quadrilateral and hexahedral meshes for use with CFD and other numerical analysis software. It is recognized for ease of use with its clean, well-managed graphical user interface and for the high quality grids that it produces. Gridgen is currently being used in industry, academia, and government labs. Gridgen v10 is available for Silicon Graphics ® workstations. Pointwise has extended Gridgen's special introductory price of $5,000 for a networked, right-to-use license through 31 December 1995.
Pointwise, Inc. is a premier supplier of grid generation software and services for the computational analysis community. In addition to developing, supporting, and marketing the Gridgen product family, the company is involved in numerous research and software development projects related to numerical grid generation.
