Detailed Description

Generates streamline data by sampling a set of user-specified fields along a particle track, transported by a user-specified velocity field.

Example of function object specification:

streamLine1
{
    type            streamLine;
    libs            ("libfieldFunctionObjects.so");

    writeControl    writeTime;

    setFormat       vtk;
    U               U;
    trackForward    yes;

    fields
    (
        U
        p
    );

    lifeTime        10000;
    trackLength     1e-3;
    nSubCycle       5;
    cloudName       particleTracks;

    seedSampleSet
    {
        type        uniform;
        axis        x;  //distance;
        start       (-0.0205 0.0001 0.00001);
        end         (-0.0205 0.0005 0.00001);
        nPoints     100;
    }
}
