need help with manifold analysis in fluent
 
hi,
I'm simulating exhaust manifold of a car engine. I meshed the model without errors.. The part where i'm struck is the boundary conditions..

I really need some guidance for modeling,

The recurring boundary conditions based on the crank angle and the firing order.. Like at a certain crank angle based on the firing order, the boundary conditions have to change to other manifold. like the manifold which was inlet at some time should change as a wall after some crank angle, and the appropriate manifold should be an inlet..

this is where i'm struck... about how to write the recurring boundary conditions to a manifold based on crank angle and firing order..

i really need help with this plzz..
