megatron24 is on a distinguished road
Hello everyone..
I am working on an Intake manifold design and need to do a transient analysis on either Fluent or CFX to know exactly the pattern of air moving inside.

Basically, I am clueless and need urgent help with how to simulate the valves movement at the runner's end of the intake....

I have a pressure-time table for 4 cylinders but when i apply boundary conditions using pressure table at runner ends and simulate, the air flows only in one cylinder..

can you please guide me what boundary conditions should i use at runners to simulate the air flow??
