Gridgen Extends Support for WIND and Cobalt

FORT WORTH, TX (23 April 2004) – Pointwise released Gridgen Version 15.03. This latest release of our CFD meshing software includes a native interface to the new unstructured WIND CFD solver and a double-precision option was for the Cobalt CFD solver interface. Additionally, Gridgen's Merge command, used for fault-tolerant meshing of sloppy CAD models, was enhanced with the addition of a command for explicitly specifying how the merge should be performed.

"Gridgen has been used to generate meshes for the structured grid version of the WIND solver and its predecessors since the late 1980s," said John Steinbrenner, Pointwise's Vice President for Research and Development. "We're glad to continue supporting WIND and its new unstructured mesh capabilities."

Gridgen's native interface to the Cobalt solver now provides the optional capability to export the mesh in double precision for high fidelity simulations with extreme ranges of mesh cell size. Also, the interface was enhanced so that it uses significantly less memory during Cobalt file export - up to twenty times less on some test cases.

Gridgen tolerates CAD model faults while meshing. Instead of forcing engineers to repair gaps and overlaps in the geometry to construct a watertight solid, Gridgen lets the geometry be meshed as is. During the meshing process, Gridgen applies a suite of highly automated, global and local tools to merge the mesh over gaps in the CAD geometry. A new tool was added to the Merge feature set. This new tools lets the user explicitly control how the merging is performed.

Pointwise, solving the top problem facing engineering analysts today: mesh generation for computational fluid dynamics (CFD). Gridgen runs on Unix, Linux, and Windows; generates structured, unstructured, and hybrid grids; and interfaces with CFD solvers such as Fluent, STAR-CD, and CFX as well as many neutral formats like CGNS ( Large manufacturing firms and research organizations worldwide rely on Gridgen as their complete preprocessing toolkit.
