This document summarizes baffle meshing techniques using cfMesh and snappyHexMesh in OpenFOAM. It discusses applying cfMesh to add thickness to baffle plates in a CAD model, comparing meshing results between the original and thickened baffles. The document also mentions upcoming work on meshing other parts like rotors and stators, setting up rotating zones, and running simulations.
