Creating a Velocity Profile at Inlet

Hello,
I am relatively new to openFOAM and and under rather tight time constraints (university project). I wish to model the flow around a single pier in a flume that is 10m long. To try and reduce running time I want to reduce the length of the flume in front of the pier. I have read that if I run the simulation without the pier geometry I can get a velocity profile for the water in the flume at any point (I want it just in front of the leading edge of the pier). I can then extract this profile, put my pier geometry into the mesh and use the velocity profile as the inlet boundary conditions? Is this possible in openFOAM and is it feasible? Stu |

Ich don't know how exactly to do it. But I know that you could peform a simple Channel flow, long enought to geht your Profile. Then use the Outlet (Patch) Profile and set it as your inlet condition oft your Project. Hope it gives you a hint... Sent from my ONEPLUS A3003 using CFD Online Forum mobile app |
