Sorry mate, you're just going to have to work through the tutorials ... The cyclic BC is for doing only a single part of a repeating geometry such as a cascade. To try to avoid divergence, start your calculations using first order upwind differencing, and use more conservative relaxation parameters. Go read the manual, the Ace relaxation settings are not entirely intuitive.
