PyFoam compares fields from the test case for 2 solver versions
 

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

Moving ahead but stuck with SamplePlot parsing sets (which drives comparison method).

My sets look like (in OF10)

sets(
data(
type lineUniform;
axis distance;
)

);

surfaces ();

fields ( p );

as result I see data.xy ascii-files per timestep with 2 columns: distance and p.

The command
pyFoamSamplePlot --dir=postProcessing/sample --info

returns list with steps, list with a single line, and unfortunately empty list of fields.

Why SamplePlot does not see the samples?
