• hexahexa_2x2x2.mesh, the MESH file.
• hexahexa_2x2x2.nc, the NETCDF file created by the program.

PART is a large 3D object including 28,694 vertices, 14,890 triangles, 150,779 tetrahedrons, 50 corners, 1905 edges and 1905 ridges.

• part.mesh, the MESH file.
• part.nc, the NETCDF file created by the program.
