operating pressure problem
 

I simulate two parallel flow to observe heat transfer between them. the problem is that operating pressure for these flows must be different. for one of them it must be 2.9 atm and for the other one it must be 1 atm. how can I define two different operating conditions in Fluent?

it is urgent, please help me

thank you in advance...

Re: operating pressure problem
 

can only have one operating pressure in fluent so both must be relative to this. However patch in the local cell zone pressure and control at the boundaries.
