Probing line data into a single file

Hello,

I am probing line data in openfoam, and use the following code within the controlDict file.

Code:

probeLineData  

  {

    type sets;

    enabled true;

    verbose true;

    interpolationScheme cellPoint;

    outputControl timeStep;

    outputInterval 1;

    setFormat raw;

    fields (U); // the fields

    sets

    (

      X1 // line name

        type uniform;

        axis y;

        start           (-1 -1 0);

        end             (-1 1 0);

        nPoints         50;

      }

    );

}

When I use this, each line data probed are written into a different time directory within postProcessing folder. However, I would like the line data to be written into a single file so that I can easily post-process the time history of the line data.

Does anyone know a way to do this? or Can you suggest me any solution?

Cheers,
Cyln

Hi!

Honestly I don't know if you can do that, maybe you can. But if you use "setFormat gnupot;", then you can plot the different time levels in the same figure easily.

You can use singleGraph function. Include this line in your controlDict:

Code:

functions 

{ 

    #includeFunc  singleGraph

}

Then use this command to copy the dictionary to your system:

Code:

cp $FOAM_ETC/caseDicts/postProcessing/graphs/singleGraph system

Just modify the dictionary based on your specifications.
