How to Use snappyHexMesh in OpenFOAM | Mesh Complex Geometries Step by Step

Learn how to use snappyHexMesh in OpenFOAM to generate a mesh for complex geometries. In this tutorial, I explain the snappyHexMesh process step by step using a case with a rotating inner cylinder inside an outer cylinder. We go through the geometry, mesh refinement, castellated mesh, snapping, and the final mesh. A practical tutorial for anyone getting started with snappyHexMesh and complex mesh generation in OpenFOAM. #OpenFOAM #snappyHexMesh #CFD #Meshing #MeshGeneration #CFDTutorial
