You don't need to write for several cycles. You need to put it in a loop and repeat the cycles untill converges. I wrote it in a new version of Fortran (fortran 95, or 2003). You need to use recursive subroutine (not exist in fortran 77). It can be V-cycle or W cycle, based on your parameter. If gamma=1 , it will be V cycle, 2 or more, will be W. Because of some copyright restrictions, I am not allowed to send the code. But if you have any problem, pls feel free to ask.

It is possible to write several stages, but it is really not necessary. You can put a loop from 1 to 7, replacing of writing 7 stages. email: mohamednabi@hotmail.com
