Scripting and Customization for CFD Mesh Generation Software

In order for mesh generation to be an integral component of your CFD process, you need meshing software that can be customized and proceduralized. Pointwise’s Glyph scripting language gives you the ability to automate all or parts of the meshing process with macros and templates.

Meshing for Control, Quality, and Automation

You can generate structured multi-block, unstructured, hybrid, and overset meshes for viscous simulations with precise control over point placement and clustering to get the resolution you need. At the same time, Pointwise’s core meshing methods produce cells of high quality to ensure convergence and accuracy in your CFD solution.

Using Pointwise’s Glyph scripting language, you can automate most or all of the mesh generation process by writing macros and templates. And the software’s plug-in SDK gives you the ability to write a mesh exporter customized to your CFD solver. Between Glyph and plug-ins, you can customize the entire meshing process from geometry model import to flow solver export.

Big Wave Surfboard Optimization Using Pointwise and CRUNCH CFD

Working with one of the world's top big wave board shapers, engineers at CRAFT Tech have applied computational fluid dynamics (CFD) within a design optimization process, employing a genetic algorithm to evolve the design of a big wave surfboard. In this article, we will explore the design framework that allowed over 100 design iterations to be explored, resulting in a higher speed, lower drag, big wave surfboard design.

Automating Geometry and Mesh Generation for Heat Exchangers

Automating Geometry and Mesh Generation for Heat Exchangers

Maura Gallarotti, a master's student at KTH Royal Institute of Technology in Sweden, used Pointwise Glyph scripting to quickly generate families of candidate heat exchanger designs and to perform parametric studies by changing the dimensions of several geometrical parameters to assess the effect of these parameters on cooling efficiency. With no experience using Pointwise and having never heard about Tcl/Tk or Glyph she was able to write a script to completely automate the grid generation process in less than a week.

Meshing the 24th IMR Fender® Jazzmaster Guitar and the Abdominal Atlas

Meshing the 24th IMR Fender® Jazzmaster Guitar and the Abdominal Atlas

Last month several Pointwise engineers attended the 24th International Meshing Roundtable (IMR) held in Austin, Texas. We brought two grids generated for two benchmark geometries provided by the IMR steering committee. The grids were made by Carolyn Woeber, Travis Carrigan, and myself. We were pleased to hear that the grids were recognized both for their technical merit and striking visuals - they had won the Meshing Contest award.

Integrating OpenVSP and Pointwise for High-Fidelity CAE in Conceptual Design

Integrating OpenVSP and Pointwise for High-Fidelity CAE in Conceptual Design

Pointwise recently attended the OpenVSP Workshop 2015 hosted by NASA Langley and demonstrated Glyph scripting for automated viscous anisotropic meshing of a transport aircraft from OpenVSP. With recently added support in OpenVSP 3 for exporting models as STEP files, users now have an easy way to use an analytical geometry representation in Pointwise. The Glyph script automates the meshing process and provides a recipe for recommended meshing practices that new users can adopt when creating their own meshes in Pointwise.
