periodic condition at parallel solver

Amer Mahmood

Dear Fluent users,

I am simulating water flow in rectangular duct with periodic B.C. at inlet & outlet. If I read the grid in Fluent6.2 on single cpu, grid check command gives no errors. On the other hand if i read same grid using 4cpu parallel machine, grid check gives warning and fails. The printed warning is "incorrect face count".

I will be thankful if any of you can tell me the solution to this problem.

Thanks

Amer
