First of all, thank you Rob for your immediate reaction to my question! It really helped.
I fixed the problems based on your advice but another one occurs. When i manually create the periodic b.c. with the left and right surcafe of the domain, i leave the box (matching, mapped, coupled) unchecked. So ansys creates a pseudo-surface to unite the two surfaces i impose the interaction and the periodic bc. My problem is that i want to specify the periodic conditions with 0 mass flow rate and 0 gauge pressure. But when i run the simulation occurs a floating point exception from the first iteration
The cause of this error might be the type of the pseudo-surfaces created?? (they are left to wall). If not do you have any other ideas?
Thanks a alot for your help and your time!
