I am trying to sample the field values on an internal curved surface. The way I managed to sample the values was using the function object surfaceInterpolate in controlDict. For this I created a dummy surface where I needed the sampling and defined it as "empty" physical surface, and correspondingly making it empty in each 0 folder files.

functions
{
    dummySurfaceData
    {
        type            surfaceInterpolate; //surfaceFieldValue;
        libs            ("libfieldFunctionObjects.so");
        writeControl    writeTime;
        writeFields     true;
        surfaceFormat   raw;
        regionType      faceZone; //faceZone;
        name            dummySurface;
        operation       none;
        fields
        (
            (p pNear) (T TNear) (U UNear)
        );
   }
}

If I open the results in paraview I can see the data on the faceZone but I did not find any file written for the dummySurface field values in the case folder. All I see is the pNear, TNear and UNear files in the time folders but the entries for the dummySurface are none in those.


So am wondering if there's any way I can write these sampled field values to a (csv) file?
