boundary condition
 

hi
I try to analysis the unsteady flow in 2d centrifugal pump in FLUENT. I'm going to use static pressure as boundary condition in outlet. I'm going to specify pressure in just one face of a single grid in the outlet line.I try to mark a cell(adapt>region) in outlet and then separate the outlet line with that cell.now I have 2 outlet line,one is the primary outline and the second one is the cell face and i don't know how deal with the primary one(I just wanna specify p in the second one). I don't know if this method is right or not. I've really confused. It's kind of you,if you could help me.
