Gridgen Version 14 Released

Features Glyph Scripting and Native CAD Import

FORT WORTH, TX (3 May 2002) – Pointwise, Inc. today began shipping Gridgen Version 14, the latest release of its flagship CFD meshing software product, to customers and distributors worldwide.

The cornerstone feature of Gridgen Version 14 is Glyph, a new Tcl-based scripting language. Using Glyph, engineers can create customized meshing applications and utilities that significantly reduce the effort required to perform a computational fluid dynamics (CFD) analysis. “Glyph helps both expert and novice analysts” said John Chawner, Pointwise's president. “The novice analyst can use a customized, Glyph-scripted application that hides all the meshing details while the expert analyst can use Glyph to customize Gridgen for his or her way of working. In both cases Glyph allows the analyst to concentrate on the product, not the mesh.”

Gridgen Version 14 also features Native CAD Import, the ability to bypass computer aided design (CAD) neutral files like IGES and import geometry data from the native CAD file formats such as CATIA and Pro/ENGINEER without using a CAD license. “Native CAD Import eliminates one source of geometry translation errors” said John Steinbrenner, Vice President of Research and Development. “It also removes one step, exporting the neutral file, from the analysis process.” Gridgen's Native CAD Import was developed using Spatial Corp.'s ACIS Exchange technology. ACIS SAT and STEP AP203 file import are also supported.

Other new features in Gridgen Version 14 include support of triangular faceted database models in STL format, topology simplification through automatic joining and decimation of surfaces meshes, baffles (faces internal to a volume mesh), a mirror transformation, several new grid diagnostic functions, integration of the grid quality examination command with the elliptic PDE methods for structured grids, and export filters for the CFD++, CRUNCH, and NCC CFD solvers.

Pointwise, Inc. is solving the top problem facing engineering analysts today: mesh generation for computational fluid dynamics (CFD). Large manufacturing firms and research organizations worldwide use Pointwise's Gridgen software and services to create the "digital geometry" that enables computer simulation of a product's performance in a fluid environment.
