Tracking through an inverted region of the mesh happens in a reversed direction relative to a non-inverted region. Usually, this allows the tracking to propagate normally, regardless of the sign of the space. However, in rare cases, it is possible for a straight trajectory to form a closed loop through both positive and negative regions. This causes the tracking to loop indefinitely. To fix this, the displacement through inverted regions has been artifically increased by a small amount (1% at the moment). This has the effect that the change in track fraction over the negative part of the loop no longer exactly cancels the change over the positive part, and the track therefore terminates. |

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
