Default pressure change in CFX 11

Hi,

I'd like to implement a pressure change between two faces with a domain interface in CFX 11. So I created an domain interface between the two sides and as Interface Models I have the choice between "General Connection" and "Translational Periodicity". In both options I can input a pressure change in Pascal. My problem is that I don't really know what to choose from these two things. Has anybody a good example or tutorial for pressure change in CFX?

Thanks for your help
