currently i'm doing CFD simulation on parson Nozzle blade using CFD software (GEOM,ACE and VIEW)..my lecturer ask me to set for cylic on the boundary condition of the blade..i wanna know what is the purpose of cyclic?

when diverging occurs, what should i do to make it converge?

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.

hye there..

can anyone give me links to CFD website especially that contain journals about CFD..if possible can anyone give me their sample thesis about CFD..

you can see www.cfdesign.com for the papers published usin CFD.
