Traditionally, CFD flow solvers have not had access to the geometry model, only the mesh built on it. Access requires a solid modeling and NURBS (non-uniform rational B-Spline) geometry kernel in order to work with the types of geometry models produced by modern computer-aided design (CAD) systems. Because CFD solvers consume large amounts of compute resources (for example, meshes with hundreds of millions of points), a geometry kernel for a CFD flow solver should be relatively fast and small. Mesh adaptation is one scenario in which a CFD flow solver would use a geometry kernel to ensure that points moved or inserted for solution accuracy remain constrained to the geometry model.
"Pointwise has developed its own geometry kernel over the past several decades," said Nick Wyman, director of applied research. "Recently we launched Project Geode, a beta program through which we are sharing the core of our geometry kernel with select customers and partners. The Project Geode kernel, a 4th generation solid modeling and geometry kernel written in C++, will form the basis of the proposed effort.”
Subsequent to successful contract negotiation, work is expected to begin later in 2018. In the interim, Pointwise will continue with the Project Geode beta program about which more information can be found at www.pointwise.com/geode.
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®, 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.
