About snappyHexMesh

  • 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.
