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.
