Meshing Solutions Using Pointwise's CFD Mesh Generation Software

Meshing Solutions Using Pointwise's CFD Mesh Generation Software

From geometry model import to flow solver export, Pointwise provides tools for every step of the meshing process including mesh editing down to the individual grid point to global mesh metric evaluation. You can even customize the software by adding your own file readers and writers using the plugin API.

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.
