“Pointwise Version 17 is a significant milestone in our development of CFD software,” said John Chawner, Pointwise’s president. “It represents the culmination of a multi-year effort to consolidate all our technology within the new Pointwise software framework. With more automated methods, a broader scope of functionality, and a new level of usability, customers now can hurdle one of the primary barriers to effective CFD – the time required to generate a quality mesh.”|
Pointwise’s T-Rex technique (anisotropic tetrahedral extrusion) is a highly-automated method for generating a hybrid mesh suitable for resolving boundary layers, wakes and other features of a viscous flowfield. T-Rex extrudes layers of high-quality tetrahedra (with included right angles), avoids collisions with layers extruding from adjacent geometry, and optionally combines the layered tets into prisms. The implementation in Pointwise automatically ensures consistency of the volume mesh with the adjacent surface meshes, something which previously had to be managed manually.
This new Pointwise release also includes the ability to read geometry data from native CAD formats including ACIS, CATIA V4, CATIA V5, NX, Parasolid, Pro/ENGINEER, SolidWorks, and STEP. Importing directly from a native format bypasses the requirement to produce an IGES file and avoids the possible errors introduced by translating to an intermediate format. The readers, bundled into Pointwise, operate without a license of the CAD software.
Also included in Pointwise Version 17 are the ability to group entities for ease in selection and manipulation, the ability to easily re-extrude grids generated with the software’s traditional style extrusion methods, the option to restrict application of grid algorithms to a portion of the overall grid using subgrids, updated exporters for several CAE formats, and much more.
Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for computational fluid dynamics (CFD). The company’s Pointwise and Gridgen 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 scripting languages that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.
