Application Pointwise released the case study, 28X Increase in Simulation Speed by Using Pointwise Meshes which explains how in collaboration with NASA GRC, ADSCFD applied the ADSCFD GPU accelerated CFD with Pointwise meshes to reduce simulation times by 28x.

The ADSCFD GPU accelerated flow solver offers a 28X speedup over the equivalent CPU based simulation for the analysis of novel casing treatment geometries over an embedded stage when using Pointwise’s hybrid and unstructured grids. Results are encouraging as the analysis shows the complexity of the flow physics and highlights how difficult it will be to design casing treatments effectively without fast and accurate CFD.

This is a key enabling technology for bringing novel casing treatment designs into next-generation gas turbine engines. Coupled with the ability to connect structured multi-block meshes to unstructured meshes, automate the process so that new designs can be easily swapped in and out and compared, the path to optimization is imminently achievable.

Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today – reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured, overset and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT® and CFX®, STAR-CCM+®, OpenFOAM®, and SU2 as well as many neutral formats, such as CGNS; runs on Windows, Linux, and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Manufacturing firms and research organizations worldwide have relied on Pointwise as their complete CFD preprocessing solution since 1994.

ADSCFD delivers aerospace-class CFD for the global turbomachinery industry. Built on the innovations of Ron-Ho Ni and rooted in decades of cutting edge aerospace application, the ADSCFD solution suite enables turbomachinery designers to tackle a wide range of compressor and turbine flow problems with confidence. The company is privately-held and headquartered in Danville, California. For more information, visit
