CFD Meshing Software offers multiple modeling capabilities.
Press Release Summary:
To address issues associated with CAD-CFD data exchange, Gridgen v15.07 enables users to create trimmed surfaces and add or remove edges from trimmed surfaces. IGES file export capability saves analysis-ready geometry in CAD-standard file format for re-use in other CAE disciplines. Structured, unstructured, and hybrid grids can also be exported to IGES files, allowing analyst's shape changes to be sent back to CAD designer as updated design geometry.
Original Press Release:
Gridgen Version 15.07 Released with More Geometry Modeling Capabilities
Trimmed Surface Modeler, IGES Export, and CATIA V5 Import Position Gridgen as CFD Geometry Hub
10 May 2005 - Pointwise, Inc. released Gridgen Version 15.07 today. This latest release of CFD meshing software features major additions to Gridgen's geometry modeling capabilities including trimmed surface creation and IGES export.
The ability to create trimmed surfaces and add or remove edges from trimmed surfaces solves a major problem faced by CFD analysts - how to work with the untrimmed or poorly trimmed geometry that is obtained from a CAD system. "Lost trimming information, due to tolerance issues during translation, is a notorious source of problems for the analyst in the CAD-CFD data exchange" said John Chawner, Pointwise's president. "With Gridgen V15.07, the trimmed surfaces can be recovered easily using these new techniques." For the analyst creating entire models within Gridgen or supplementing existing models with new geometry, more complex and realistic models can now be created using trimmed surfaces.
Several new geometry import/export capabilities let Gridgen assume the role of the analyst's "geometry hub". Using the new IGES file export, the analyst can save their analysis-ready geometry, including layers, names, colors, and other organizational data, in a CAD-standard file format for re-use in other CAE disciplines such as structural mechanics, thermal, and electromagnetics. IGES export is especially useful when Gridgen's Native CAD Readers have been used to bring together design geometry from a variety of sources including Pro/ENGINEER®, Unigraphics®, CATIA V4®, and the newly-added CATIA V5®. Grids can also be exported to IGES files, allowing the analyst's shape changes to be sent back to the CAD designer as updated design geometry.
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 Fluent, STAR-CD, and CFX 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.
