SnappyHexMesh vs CFMesh | Comparing meshing on a rotated cube

In this lecture, we continue exploring meshing in OpenFOAM using SnappyHexMesh. We first demonstrate how it works well with Cartesian-aligned geometries, but struggles when the geometry is rotated. We then compare the results with CFMesh, another open-source meshing tool, and show how feature extraction and local refinements can significantly improve mesh quality. Topics covered: Creating a cube geometry using Gmsh. Running blockMesh and SnappyHexMesh. Issues with meshing rotated geometries. Snapping and castellated mesh stages explained. Introduction to CFMesh and its minimal setup. Using feature extraction and local refinement in CFMesh. This tutorial will help you understand the strengths and limitations of SnappyHexMesh and when to consider using CFMesh for better results. 0:00 Introduction – Challenges in SnappyHexMesh and OpenFOAM 0:36 Creating the Cube Geometry in Gmsh 2:04 Generating Surfaces and Extruding the Cube 3:36 Setting up BlockMesh and Visualizing in ParaView 5:36 Running SnappyHexMesh and Checking Mesh Quality 8:04 Rotating the Geometry – Snapping and Layer Issues 11:21 Understanding Snapping Errors and Mesh Validation 14:31 Introduction to CFMesh and Setup Process 16:28 Creating and Running CFMesh – First Results 19:59 Refinement, Feature Extraction & Final Comparison Keywords: OpenFOAM mesh tutorial, SnappyHexMesh OpenFOAM, CFMesh OpenFOAM, Gmsh to OpenFOAM, OpenFOAM meshing techniques, SnappyHexMesh issues, SnappyHexMesh vs CFMesh, OpenFOAM geometry setup, OpenFOAM blockMesh guide, OpenFOAM mesh generation, OpenFOAM mesh quality, How to fix SnappyHexMesh errors, SnappyHexMesh snapping problem, Boundary layer meshing in OpenFOAM, Mesh refinement OpenFOAM, Feature edge extraction OpenFOAM, CFD mesh tutorial, Open-source meshing tools, Gmsh mesh export STL, ParaView visualization OpenFOAM, OpenFOAM, CFD, SnappyHexMesh, CFMesh, Gmsh, BlockMesh, Meshing, OpenSourceCFD, Engineering Simulation, ParaView
