- snappyHexMesh is a robust OpenFOAM application for mesh generation.
- It creates computational mesh from a surface CAD model.
- No model parts connectivity is required.
- The model should be “waterproof” or at least only tiny holes are allowed.
- Many options allow wide field of applicability.
- snappyHexMesh checks and evaluates mesh quality parameters.
- Surface model must be provided, e.g., in .OBJ or .STL format.
