boundary condition
 

Hi friends
I want to simulate pipe that has a developed condition at the inlet.and exit of pipe has a outflow condition.for fully developed boundary condition at the inlet of pipe,what can i do?
thanks

You need to get the fully developed boundary condition from an additional simulation. Create a pipe and set inlet and outlet as a periodic boundary condition with a certain target pressure drop or mass flow rate. If this is converged you can store the outlet profile and load it to any other simulation as an inlet profile.
