Dear All,
I was not able to find such discussion in the forum.
We intend to adjust the solver and verify it against generic cases, say, by differences in velocity field.
I am sure that PyFoam is able to do it, but it comes with too short examples and manuals.
The example runPitzDailyBasic.py has in postRun-function comparison between data and reference data. But I do not understand, how this data extracted from the case.
Should I add velocity field from the specific time step to runInfo of CTestRun object? How?
Or should I save the velocity field without PyFoam and use it in comparison afterwards?

Thank you
