Let's talk about overset meshes | A general overview with CFD examples
😎 Overset meshes: a benchmarking case, a couple of examples, and a few comments on best standard practices. The concepts introduced in this video apply to any CFD solver with overset meshing capabilities, including OpenFOAM and Ansys Fluent.
🤔Overset meshes (OM) are also known as overlapping grids, overset composite grids, composite overlapping meshes, chimera meshes, patches grids, composite grids, relaxed multi-block meshes.
