Overview of snappyHexMesh SnappyHexMesh, which the Hex-dominant meshing algorithm type is based on, is a mesh generation tool in the OPENFOAM® open-source software. This tool generates three-dimensional unstructured or hybrid meshes consisting of hexahedral (hex) and split-hexahedra (split-hex) elements. Besides the Standard automatic meshing tool, which generates a hybrid mesh of both tetrahedral (tet) and hexahedral … Continue reading Background of Hex-dominant Meshing
