The refine command is used to refine the mesh. The mesh refinement can be isotropic or directional over the entire domain or portions of the flow domain.



refine domain direction



Valid entries for domain are: all (for entire mesh) | set set_name (name of the set eg: billet).
For boundary element sets, the set_name will be: {BC on bcname}, where bcname is the name of the boundary given in the *.grf file.
Valid entries for direction are: iso (isotropic refinement) | xi | eta | zeta | normal

 normal indicates that the refinement is normal to a boundary and will work only if the set is a set of elements on a given boundary.
