BlockRanger is a fully interactive, volume mesh generation plug-in for the Rhinoceros 5.0 3D CAD system.  BlockRanger converts Rhino 5 solids into blocks of high-quality hexahedral (brick) elements for use with most engineering analysis packages that require hexahedral meshing and a strict control of element quality, spatial distribution, and orientation. BlockRanger is included with the purchase of a Griddle license at no extra cost.


  • BlockRanger is a general-purpose interactive all-hexahedral mesh generator for computer-aided engineering.  Its meshing applications range from fluids and structures to biomedicine and geosciences.
  • BlockRanger is surprisingly easy to learn and to use.  If you know Rhino, you already know how to use BlockRanger!
  • BlockRanger is a plug-in to Rhino 5.  Building meshes is as easy as selecting an assembly of contiguous 4-, 5-, or 6-sided solids and clicking on the BlockRanger icon.
