+> **RZAMR **uses an octree type refinement applied to an existing hexahedral
+mesh to all nodes in a specified region.&nbsp_place_holder; No additional
+elements are kept,&nbsp_place_holder; the intention is that the resulting node
+distribution will be passed to** **connect to generate a tetrahedra mesh.

+*&nbsp_place_holder; region_name&nbsp_place_holder;&nbsp_place_holder;&nbsp_place_holder; name of region to refine.&nbsp_place_holder; If blank,&nbsp_place_holder; all regions will be refined.&nbsp_place_holder; An element will be refined if any node of the element is in the specified region.   
+*&nbsp_place_holder; number_of_levels&nbsp_place_holder;&nbsp_place_holder;&nbsp_place_holder; is the number of times the refinement will be performed.&nbsp_place_holder; After each level, the code will determine which of the new nodes are in the specified region and will refine the associated elements.&nbsp_place_holder; Default is 1.
