Control volume renumbering for GMRES
 
Dear friends:
I am working on the unstructured cartesian grid, the algebraic equations was solve by the GMRES method, but the matrix was not renumbered.
could you please tell me which alogrithm should i use to renumber the unsturectured grid system so as to improve the GMRES efficiency.
Regards
