😏 This is another take of the cylinder case (vortex shedding), which we know and love, but with three component meshes.
👍 We also introduce some best practices within OpenFOAM and we compare the solution with the outcome of Ansys Fluent 2023.
🤔 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.

😵‍💫 To better follow this tutorial, we advise you to watch first the following presentation,
