hi everyone,

I would like to calculate the x,y plane average profile of a scalarField T(x,y,z)
i.e. T(x,y,z) -> T_avg(z)
I did my calculation in parallel with 5 regions from time 0 to 1200. Data is written every 300steps, such that my data are contained in case/processor{0..23}/{0..1200..300}/region{1..5}/T

The problem is, I execute the command

funkyDoCalc -time 1200 system/region2/postDict -region region2

but only the time = 0 (initial condition) is being calculated.

Any help would be appreciated!! Thank you

Details:
I follow the post,
Averaging along an axis.. swak4foam?

PostProcessing for finished calculation

and made a file called postDict containing:

avgTDistributionZ {
type swakExpressionAverageDistribution;
libs (
"libOpenFOAM.so"
"libsimpleSwakFunctionObjects.so"
"libswakFunctionObjects.so"
"libgroovyBC.so"
);
writeStartTime no;
verbose true;
outputControlMode outputTime;
valueType internalField;
expression "T";
weight "vol()";
mask "true";
abscissa "pos().z";
binNumber 54;
valueIfZero 0;
dynamicExtremesAbscissa false;
minAbscissa 0;
maxAbscissa 150;
accumulations ( average );
}

and I tried to execute the commands,

funkyDoCalc -latestTime system/region2/postDict -region region2

and

funkyDoCalc -time 1200 system/region2/postDict -region region2

both of them give the same bash output and seems calculated the time = 0 only (but the average should not be 0, internal field is set to be 300).

Hi, I am wondering if you were able to resolve the problem. Thanks.
