WebPolyhedral unstructured mesh adaptation (PUMA) in Ansys Fluent automatically refines the polyhedral mesh to resolve fine details, while leaving coarser mesh in place to help accelerate solve times. WebPolygonal and polyhedral elements: Shape functions and meshes. The development of Galerkin finite element methods on arbitrary polygonal and polyhedral elements to solve PDEs is pursued. The origins of this approach can be traced to Wachspress basis functions, which is a particular generalization of finite elements to planar convex polygons.

A mesh is a representation of a larger geometric domain by smaller discrete cells. Meshes are commonly used to compute solutions of partial differential equations and render computer graphics, and to analyze geographical and cartographic data. A mesh partitions space into elements (or cells or zones) over which the equations can be solved, which then approximates the solution over the larger domain. Element boundaries may be constrained to lie on internal or ext… WebJul 1, 2024 · Meshing Reentry Vehicles with GridPro.
