Gridgen Version 13 Released

Combines Structured and Unstructured Tri/Tet Meshing

Windows NT Port Soon To Follow

FORT WORTH, TX (1 July 1998) – Pointwise, Inc. today began shipping Gridgen Version 13, the latest release of its software used for grid generation and preprocessing for computational fluid dynamics and finite element analysis. This release combines Gridgen's proven structured quadrilateral and hexahedral gridding, with new automated unstructured triangular and tetrahedral meshing.

"Version 13 will put Gridgen's ease of use and high quality grids into the hands of even more engineers", said John Chawner, Pointwise's president.  "We now have a tightly integrated mesher that combines the high quality and accuracy of structured grids with the automation and time-savings of unstructured meshes."

Gridgen's triangular surface mesher saves engineers time by meshing across one or more trimmed NURB surfaces, even when there are gaps and overlaps between the surfaces.  This allows an engineer to begin meshing a CAD geometry without having to spend time cleaning up dirty geometry.  Gridgen's tetrahedral volume mesher has been developed in cooperation with Geometricon, L.L.C, which is headed by Dr. Timothy Baker, a world recognized expert in unstructured meshing.  Dr. John Steinbrenner, Pointwise's Vice President of Research and Development notes that "by combining Geometricon's technical expertise with Pointwise's ability to deliver technology as a practical tool, the users come out ahead.  They get the benefits of quality meshes that are easy to generate."

Version 13 also adds new diagnostic capabilities that lets users graphically examine several grid quality measures in order to assess the suitability of grids and identify any problem areas.  In addition to being able to display color contours of grid quality measures, users can enter pass/fail criteria and Gridgen will indicate the meshes that do not make the grade. 

Gridgen is known for its:

  • interactive interface using OpenGL graphics to run on Unix workstations from Silicon Graphics, Hewlett Packard, IBM, Digital, Sun, and coming in the third quarter of 1998, Windows 95 and NT,
  • geometry modeling tools, robust IGES import, and fault-tolerant gridding methods that let analysts work effectively with large and less-than-perfect models,
  • highly automated and wide variety of gridding methods that allow users to create good grids right from the start, and
  • filters to export grid and boundary condition data formatted for use with a wide variety of analysis software including FIELDVIEW, NASTRAN, PATRAN, UCD, VRML, STL, ADPAC, CFX-4, COBalt, FDNS, FLUENT, FLUENT/UNS, GASP, GUST, INCA, NPARC, OVERFLOW, PHOENICS, RAMPANT, SCRYU, STAR-CD, TASCflow, TEAM, VSAERO, and WIND.

Pointwise, Inc. is solving the number one problem facing engineering analysts today: mesh generation for CFD and FEA. They do this by being a premier supplier of grid generation software and services centered around the Gridgen software product.  Gridgen software is currently in use at hundreds of sites around the world including Lockheed Martin, Boeing, Northrop Grumman, Sandia and Los Alamos National Laboratories, Allison Engine Company, General Dynamics, NASA, Navy, Army, and Air Force Labs, and Raytheon.

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.  Further information on Gridgen can be obtained from Pointwise's World Wide Web site,
