I'm trying to get probes and residuals working in chtMultiRegionFoam but it does not seem to work. The postprocessing/probes/0 directory is not created and nor is any data.

I tried using probes with the pitzDaily tutorial and that worked fine. I also reviewed the user guide but found nothing to assist me.

So I'm assuming that there is something different required for a multi-Region case, but i can't work out what it it. I've tried placing probes file in system/*region* directories but that dose not help. I can't see anything in the log files either.

Any help would be welcomed in generating probes for multi-region cases.


In the controlDict I have

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    location    "system";
    object      controlDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

application     chtMultiRegionFoam;

startFrom       startTime;

startTime       0;

stopAt          endTime;

endTime         200;

deltaT          0.01;

writeControl    adjustableRunTime;

writeInterval   1.0;

purgeWrite      0;

writeFormat     binary;

writePrecision  6;

writeCompression off;

timeFormat      general;

timePrecision   6;

runTimeModifiable true;

maxCo           1.0;

maxDi           10.0;

adjustTimeStep  yes;

functions
{
    #includeFunc  probes
    #includeFunc  residuals
}


// ************************************************************************* //

In the probes file i have

\*---------------------------------------------------------------------------*/

#includeEtc "caseDicts/postProcessing/probes/probes.cfg"

fields (p T);
probeLocations
(
    (0.0 0.05 0.05)
    (0.095 0.05 0.05)
    (0.105 0.05 0.05)
    (0.15 0.05 0.05)
);

I've managed to get it working with the below code. It seems that you have to define a probes function for each region and declare the locations in the controlDict rather another file.

Is there a neater way of doing this. Is there a way of using a separate file defining the coordinates?

The below is my new controlDict entry:

functions
{
    probes_cubeA
    {
       // Type of functionObject
       type probes;

       // Where to load it from (if not already in solver)
       functionObjectLibs ("libsampling.so");
       outputControl   timeStep;
       outputInterval  1;

       region cubeA_solid;

      // Fields to be probed. runTime modifiable!
       fields
       (
       T
       );

       // Locations to be probed. runTime modifiable!
       probeLocations
       (
       ( 0.0 0.05 0.05)
       ( 0.05 0.05 0.05)
       ( 0.1 0.05 0.05)
       ); 
    }


    probes_cubeB
    {
       // Type of functionObject
       type probes;

       // Where to load it from (if not already in solver)
       functionObjectLibs ("libsampling.so");
       outputControl   timeStep;
       outputInterval  1;

       region cubeB_solid;

      // Fields to be probed. runTime modifiable!
       fields
       (
       T
       );

       // Locations to be probed. runTime modifiable!
       probeLocations
       (
       ( 0.1 0.05 0.05)
       ( 0.125 0.05 0.05)
       ( 0.15 0.05 0.05)
       ); 
    }

};
