Starting with a CATIA model (gray) in Pointwise, an unstructured surface mesh was generated and exported to GridPro for use as geometry. GridPro created a structured, multi-block hex grid near the blades, which was exported back to Pointwise for addition of the outer unstructured mesh.
FORT WORTH, TX (30 September 2013)—Pointwise announces the latest release of its Pointwise computational fluid dynamics (CFD) meshing software, now compatible with the GridPro grid generator.
“There are a lot of interesting grid generation technologies out there and one of the most interesting – from the standpoint of structured, multi-block grid generation – is the GridPro software from Program Development Company,” said John Chawner, Pointwise’s president. “We found that customers who use both programs would benefit from file compatibility. That’s why we reached out to Dr. Peter Eiseman, PDC’s founder and president, and we agreed to collaborate on this project.”
The new release of Pointwise can import structured volume grids from GridPro’s file format so they can be integrated into a Pointwise hybrid mesh or otherwise modified. Pointwise also exports both structured and unstructured surface meshes to GridPro for use as geometry on which GridPro can generate a grid.
“I am pleased to be working with John Chawner and Pointwise on this collaboration and look forward to seeing our customers reap the benefits of our respective packages, each of which offers distinctive valuable capabilities,” said Dr. Eiseman. “Precise reliable user control is a hallmark of Pointwise and is very compatible with the topology approach of GridPro. The topology paradigm is driven by GridPro’s proprietary dynamic boundary conforming technology (DBC), which provides multiblock grids that are optimized for smoothness and orthogonality throughout the regional volume. DBC is often used to provide local resolution to accurately model localized physics in the CFD solution. To inject further control in a reliable precise manner, the user will now be able to import such grids into Pointwise where its precise controls can then be applied for further user modifications.”
Pointwise Version 17.1 R4 includes defect corrections and other new capabilities including a new native interface to the TAU CFD solver, a C++ API for writing plugins, support for OpenFOAM cell sets, and other minor features.
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.

GridPro extends the reach of multiblock grids into cases that have previously been too complex to consider and does so in a manner that provides the foundation for CFD/CAE solvers to perform at their very best. The capability is the result of the DBC technology that moves a pattern of points onto a region to yield an optimized grid. The interactive GUI automatically generates the TIL code which structurally looks somewhat like the C/C++ programming languages and provides fully automatic grid generation for each codified pattern. As such, it is worthy to note that TIL codes allow recurrent use and can be assembled in a macro fashion to form yet more exotic codes that for example can efficiently cover cases with recurrent structures.
