Hey guys,

i want to use the runtime postprocessing capabilities of OpenFOAM. Therefore, i modified my controlDict-file, it looks like:

/*--------------------------------*- C++ -*----------------------------------*\

}

The cuttingPlane-file looks like:

/*--------------------------------*- C++ -*----------------------------------*\

cuttingPlane
{
    type            surfaces;
    functionObjectLibs ("libsampling.so");
    outputControl   outputTime;

    surfaceFormat   vtk;
    fields          ( alpha1 );

    interpolationScheme cellPoint;

    surfaces
    (
        zNormal
        {
            type            cuttingPlane;
            planeType       pointAndNormal;
            pointAndNormalDict
            {
                basePoint       (0 0 8);
                normalVector    (0 0 1);
            }
            interpolate     true;
        }
    );
}

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

After a certain time-step, i checked the resulting vtk-file in paraview together with the foam-file. Unfortunately, the result of the cuttingPlane looks like nonsense :

Here is the complete domain i want to simulate:



Here you can see the domain again (this time with wireframe-representation) together with the cuttingPlane. The position of the cuttingPlane obviously seems to be correct, but the result makes no sense (for me):



Do you have a hint for me?

Best regards!

Just for your information, i think this is a known bug in OpenFoam 2.2.0. I tried it again with OpenFoam 2.2.1, and now it works!

Best regards!
