Pointwise Starts User Script Exchange Site

Posted Thu May 26, 2005 @03:51PM

Pointwise, Inc. has established the Glyph Script Exchange on their website for Gridgen users to share Glyph scripts with each other. Glyph is Gridgen’s scripting language. It is based on the Tcl scripting language and lets users have complete control over Gridgen’s meshing capabilities through a script interface.

Glyph scripts have a variety of uses. They can function as time saving utilities for changing grid spacing, number of grid points, colors of grids, and other menial tasks. Intermediate level scripts can be used for more complex jobs like creating simple volume grids and performing a suite of quality checks on a completed grid automatically. At the highest level are Glyph scripts that build complete mesh systems parametrically. Parametric scripts have been developed for turbine blades, torque converters, centrifugal compressors and pumps, high-lift flap systems for aircraft wings, submarines, and several other applications. Many more are under development.

People are free to download scripts from the website and use them. At the present time there are over 20 scripts available for download. Currently available scripts range from simple scripts for customizing Gridgen’s user interface to a high-end script for automatically gridding centrifugal pumps.

Users can also upload their own scripts to the website if they would like to share them with others. After upload Pointwise staff examine the scripts for a quick checkout before they are made available for download.

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). Manufacturing firms and research organizations worldwide rely on Gridgen as their complete pre-processing toolkit.
