FORT WORTH, TX (15 February 2013)—Pointwise announces the latest release of its Pointwise computational fluid dynamics (CFD) meshing software, which includes a refactored algorithm for agglomerating cells in a hybrid mesh. The new algorithm significantly improves the reduction in cell count. The best reduction achieved during testing was a 377 million cell mesh that was reduced to about 155 million cells.

“We continue to improve our T-Rex hybrid mesh generation technique at the request of customers,” said Dr. John Steinbrenner, Pointwise’s vice president of research and development. “This automated technique extrudes layers of anisotropic tetrahedra in the boundary layer region. The customer’s mesh size, and hence CFD solver time and memory usage, can be cut drastically by combining three adjacent tets in the extruded stack into a prism wherever possible. The refactored cell agglomeration algorithm improves on prior versions of the software.”

The refactored technique has improved the reduction of a mesh’s overall cell count relative to previous versions of the software by up to 20 percent by more robustly handling complex cell topologies. (The 20 percent improvement in cell count reduction comes from a case where 337 million cells are reduced to about 155 million.) In all cases, the refactored tet-to-prism cell agglomeration approaches the theoretical maximum of two-thirds reduction in the extruded region.

Pointwise Version 17.1 R2 includes also several smaller new features and defect corrections.

Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for computational fluid dynamics (CFD). The company’s Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX and OpenFOAM 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.
