However, I would like to view the average over say the last 100 steps, to view the statistics of the solution. Is there a way I can do this in paraFoam?

Also, how is convergence judged in this example? Normally I judge conversion in a

Maybe useful for postprocessing

During runtime, this can be done via the functions in the controlDict by adding libfieldFunctionObjects.so

No I want to do the same as a postprocessing step.

My starting point was the postChannel application, that loops over
