Unsteady LES Inlet Conditions

July 30, 2007, 18:07

Hi everybody!

I'm doing an LES study and I want to use results from a separate LES simulation as the inlet condition. It is suggested in the CFX manual but I can find no description on how to do this. The purpose is to remove the need for a long inlet where the boundary layer develops from the simulation.

Any clues?

My best guess is that I need to incorporate the results from the previous simulation in a Junction Box routine which can be called from the solver to update the inlet boundary condition.
