Gridgen Version 15.08 Now Up To 15 Times Faster

	Posted Thu July 28, 2005 @08:12AM
	Pointwise, Inc. released Gridgen Version 15.08 today. This latest release of CFD meshing software includes a major enhancement of the software’s numerical techniques for hexahedral grids. Structured hexahedral grid generation has long been one of Gridgen’s strengths. Smoothing hex grids to improve quality (smoothness, clustering, and orthogonality) involves the solution of elliptic partial differential equations (PDE). Up until recently, a simple pointwise, successive over-relaxation algorithm was used to compute the solution. In V15.08, a new multi-grid algorithm accelerates convergence of the PDE solution by up to a factor of 15, especially for large grids.

	“Gridgen has been a leader in structured grid technology for 20 years, but recently the focus of our development has been on hybrid meshing and CAD interoperability,” said John Steinbrenner, Pointwise’s Vice President of R&D. “It’s nice to be able to deliver this productivity boost to our structured grid clients.” Other new features in Gridgen V15.08 include a 20-50% increase in graphics performance, an extension of the Unigraphics Native CAD Reader to version NX 3, and an upgrade of Gridgen’s support for HP-UX on PA-RISC to version 11.11. About Pointwise Pointwise is solving the top problem facing engineering analysts today: mesh generation for computational fluid dynamics (CFD). Gridgen runs on Windows, Linux, Mac and Unix; generates structured, unstructured, and hybrid grids; and interfaces with CFD solvers such as ANSYS CFX, Fluent, and STAR-CD as well as many neutral formats like CGNS (www.cgns.org). Large manufacturing firms and research organizations worldwide rely on Gridgen as their complete pre-processing toolkit. Further information on Gridgen can be obtained from Pointwise's web site, www.pointwise.com.
