OpenFoam: time averaging velocity of a URANS Simulation

Hi there,
I'm running a pipe simulation with pimpleFoam and after the simulation I would like to average the velocity in the whole field on a specific segment of time. I know I could just use simpleFoam but the solution doesn't converge with simpleFoam. So I want to simulate with PimpleFoam check the periodicity of the Simulation and average the velocity in that period in order to get a similar result to a RANS simulation. Can anybody help me? Thank you |

Try to use fieldAverage function object.
Here is an example: Code:
fieldAverage1 { type fieldAverage; libs ("libfieldFunctionObjects.so"); writeControl writeTime; restartOnRestart false; restartOnOutput false; periodicRestart false; restartPeriod 0.002; fields ( U { mean on; prime2Mean on; base time; window 10.0; windowName w1; } p { mean on; prime2Mean on; base time; } ); } Code:
grep -R "fieldAverage" $FOAM_TUTORIALS |
