generates 3-dimensional meshes containing hexahedra (hex) and split-hexahedra (split-hex) automatically from triangulated surface geometries, or tri-surfaces, in Stereolithography (STL) or Wavefront Object (OBJ) format.
runs in parallel with a load balancing step every iteration.
mesh is generated from a dictionary file named snapyHexMeshDictlocated in the system (or constant/polyMesh for old version)
run snapyHexMesh in terminal in case folder to generate mesh
