Hi,

I am running a steady state simulation. For post-processing, I am trying to get the surfaceField using surfaceInterpolate function. Below is the functional code implemented in "system" folder. After running the simulations, I am unable to retrieve any data from it. The simulation runs correrctly.

Description
    Interpolates the volume field values to surface linearly.

surfaceInterpolate1
{
    // Mandatory entries
    type            surfaceInterpolate;
    libs            ("libfieldFunctionObjects.so");
    fields          (T TInterp);

    // Optional (inherited) entries
   
    region          patch;
    enabled         true;
    log             true;
    timeStart       0;
    timeEnd         100;
    executeControl  runTime;
    executeInterval 1;
    writeControl    runTime;
    writeInterval   1;
   
}

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

I have added the file in the controlDict as:

functions
 {

   #includeFunc surfaceInterpolate1  //File name given in system folder
 }

Where do I look for the output?

I just had a similar issue and will document the solution I found:


In controlDict:

functions
{
    surfaceInterpolate
    {
        type            surfaceInterpolate;
        functionObjectLibs ( "libfieldFunctionObjects.so" );
        log             yes;
        writeFields     yes;
        field           p;
        result          pf;
    }

}

This will interpolate the pressure p to the surfaceScalarField pf which is then available for further processing steps.
