Hello openFoam community,

I have a problem that I am trying to solve with sampling of field variable over a line. What I would like to do is to add a piece of script into my controlDict so that I can obtain the sampled fields during runtime at the same interval as the timestep. I can easily use sampleDict and the command sample to do this after the simulation has finished but I would like to achieve a much higher sampling frequency than just the write output.

At the bottom of my controlDict I have written:

functions {
   WG9 {
      type sets;
      functionObjectLibs ("libsampling.so");
      setFormat raw;
      interpolationScheme cell;
      outputControl timeStep;
      outputInterval 1;
      axis    z;
      start   (10.369 2.05 0);
      end     (10.369 2.05 1.15);
      nPoints 100;
      fields (alpha1);
   }
}

It seems to run fine without any errors but there is no output folder (I would expect a postProcessing folder to appear after simulation starts much like it does when you run the "forces" function)

Does anyone know if this is even possible what I am trying to accomplish? If so, do I appear to be missing something?
