MATHEMATICS, SIMULATION AND MODELLING
15 April 2014
Pointwise, a provider of computational fluid dynamics (CFD) software, has announced the latest release of its Pointwise CFD meshing software featuring an extension of the company’s advanced T-Rex hybrid meshing technique to generate near-wall layers of hexahedral cells.
T-Rex (anisotropic tetrahedral extrusion) is a highly automated, advancing layer technique for generating a CFD mesh with boundary layer and wake resolution. The technique extrudes layers of high-aspect ratio, right-angle-included tetrahedra outward from a surface mesh. A post-processing operation sequentially combines three successive tetrahedra into a stack of prisms. In this new release of the technique, extrusion from a quadrilateral surface mesh begins with a single pyramid, after which the usual tet extrusion begins. The resulting tets (and that first pyramid) are post-processed into stacks of hexes.
‘This new hex capability in T-Rex is just the first step of many that will vastly expand the scope of mesh types that Pointwise can generate,’ said John Chawner, Pointwise’s president. ‘We look forward to customer feedback on this first release of unstructured hex cell generation in T-Rex to guide further developments.’
Pointwise Version 17.2 also includes updated compatibility with CGNS, Fun3D, Ansys Gambit, Star-CD, and SC/Tetra; support for the OpenSUSE, Ubuntu, and CentOS Linux distributions; several productivity improvements; and defect corrections.
