"The integration of grid generation and overset grid assembly represents a vast improvement over the hodge-podge of disparate tools typically employed by practitioners of overset CFD," said Nick Wyman, Pointwise director of applied research.
"What we are releasing today for production use is the result of a multi-year research effort Pointwise conducted with funding from the U.S. Air Force’s Arnold Engineering Development Complex, Air Force Materiel Command. That research was followed by a full year of fine-tuning in preparation for release to all our customers."
The price paid for that flexibility of overset gridding is the need to ensure a sufficient degree of overlap so the CFD solver can accurately share data between the component grids. The overlap is computed using overset grid assembly software. Users of OGA software typically rely on a circuitous collection of home-grown tools that are patched together. By integrating OGA (in the form of the PEGASUS and Suggar++ software packages) with Pointwise, the entire process is made more efficient.

“Pointwise has been a proud, long-time sponsor of and participant in the bi-annual Overset Grid Symposium,” said John Chawner, Pointwise’s president. “This release of Pointwise helps us continue our integral relationship with that community.”
Other features in Pointwise Version 17.3 R1 include improved support for PLOT3D, ANSYS Fluent®, STL, and NX files, a more robust T-Rex, anisotropic tetrahedral extrusion, hybrid mesher, and several user experience enhancements.
Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today – reliably generating high-fidelity meshes. The company’s Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX, OpenFOAM, and SU2 as well as many neutral formats, such as CGNS; runs on Windows (Intel and AMD), Linux (Intel and AMD), and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.
