WebApr 25, 2024 · Unfortunately, the poly-hexcore meshes are invalid with CFX, which would be the best (IMO) non-multiblock, unstructured method. I would like to 'jump ship' from CFX to Fluent, mostly on the basis of using the poly-hexcore meshes for my complex internal flow geometries, for higher mesh quality and reduced node/element quantities. 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 external bo…
