Pointwise Version 17.2 is now available for download and production use. The main new feature in this latest release of the software is an extension of the T-Rex hybrid meshing technique to create layers of near-wall hexahedra.
Through an extension of the algorithm that post-processes the tetrahedra generated by the T-Rex advancing layer technique (anisotropic tetrahedral extrusion), the high aspect ratio tetrahedra created by extrusion from a quad surface grid can now be agglomerated into hexahedra.
At its core, T-Rex is an advancing layer technique that starts from a triangle surface mesh and extrudes layers of high aspect ratio, right angle included tetrahedra near walls, wakes, and other features. Those tetrahedra are post-processed (optionally) by combining three successive tetrahedra into a prism.
The ability to post-process the stacks of extruded tetrahedra into hexrahedra begins with a quadrilateral surface mesh off of which the first extruded cell is a pyramid. The regular T-Rex extrusion takes over from there. The cells are then post-processed into stacks of hexahedra. See Figure 1 for an example.
This extension also adds to T-Rex the ability to have an existing quadrilateral mesh serve as a boundary condition for a T-Rex prism extrusion.
In addition to Red Hat Linux, Pointwise is now supported on SUSE Linux, CentOS, and Ubuntu.
