GREPOS
GREPOS is a mesh utility program that repositions or modifies the configuration of a two- dimensional or three-dimensional mesh. GREPOS can be used to change the orientation and size of a two- dimensional or three-dimensional mesh; change the material block, nodeset, and sideset IDs; or "explode" the mesh to facilitate viewing of the various parts of the model, and several other mesh modification utilities.
