The latest release of Pointwise’s computational fluid dynamics (CFD) mesh generation software includes the ability to use regular hexahedra instead of unstructured tetrahedra in regions away from the geometry model. The software’s T-Rex (anisotropic tetrahedral extrusion) technique generates layers of hexahedra or prisms near the geometry model for boundary layer resolution. Use of regular hexahedra elsewhere in the mesh can improve the CFD flow solver’s rate of convergence and accuracy of the resulting solution.
“Voxel mesh capabilities were originally implemented in Pointwise as part of research for the U.S. Air Force related to overset grid assembly,” says Dr. John Steinbrenner, executive vice president. “We have extended voxels beyond their original intent into hex-core: an efficient, space-filling meshing technique that delivers a lot of attributes that should benefit flow solvers.”
Pointwise Version 18.3 includes several new features that further automate surface mesh generation, the ability for users to define their own keyboard shortcuts, the ability to use point clouds for mesh adaptation.
