Applications of Geometry Modeling

Preparation of geometry models for meshing is essential to all mesh types. Pointwise supports both parametric (NURBS) and faceted (STL) geometry, imports a variety of native and neutral formats and offers two techniques for meshing over gaps; fault tolerant meshing and solid meshing.

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.

Pointwise Aids Bid to Make World’s Fastest Bike

Pointwise Aids Bid to Make World’s Fastest Bike

The Human Power Team is comprised of students with a shared goal: to build a highly advanced recumbent bicycle capable of breaking the world record for the fastest human alive. We will put our bike, the VeloX, to the test for the seventh time in the annual World Human Powered Speed Challenge in Battle Mountain, Nevada. This year the Human Power Team will focus purely on the world record for women, which was set at 121.81 km/h by Barbara Buatois in 2010.

Mesh Generation for the NASA HL-CRM

Mesh Generation for the NASA HL-CRM

Pointwise is supporting two AIAA workshops (the 3rd High Lift Prediction and the 1st Geometry and Mesh Generation Workshop) to be held prior to AIAA Aviation in June 2017. We generated several type of meshes (unstructured, hybrid, hybrid overset, and high order) for the NASA High Lift Common Research Model that are described here.

OpenVSP and Pointwise Work Together to Simplify CFD on New Vehicle Designs

OpenVSP and Pointwise Work Together to Simplify CFD on New Vehicle Designs

OpenVSP is an open source, parametric modeler used to quickly capture design intent so geometry information is easily provided in the appropriate form for various uses, including CFD. Therefore, several approaches were explored by which OpenVSP and Pointwise could be integrated to automate the volume meshing process for CFD.
