Detailed Description

This function object 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");
    ...
    setFormat       vtk;
    trackForward    yes;
    fields
    (
        U
        p
    );
    lifeTime        10000;
    trackLength     1e-3;
    nSubCycle       5;
    cloudName       particleTracks;
    seedSampleSet   uniform;
    uniformCoeffs
    {
        type        uniform;
        axis        x;  //distance;
        start       (-0.0205 0.0001 0.00001);
        end         (-0.0205 0.0005 0.00001);
        nPoints     100;
    }
}
Usage
Property Description Required Default value
type Type name: streamLine yes
setFormat Output data type yes
U Tracking velocity field name yes
fields Fields to sample yes
lifetime Maximum number of particle tracking steps yes
trackLength Tracking segment length no
nSubCycle Number of tracking steps per cell no
cloudName Cloud name to use yes
seedSampleSet Seeding method (see below) yes

Where seedSampleSet is typically one of

uniform : uniform particle seeding
cloud : cloud of points
triSurfaceMeshPointSet : points according to a tri-surface mesh
Note
When specifying the track resolution, the trackLength OR nSubCycle option should be used
