Class
    Foam::CorrectionLimitingMethods::relative

Description
    Correction limiting method based on the relative particle velocity.

    This method limits the velocity correction to that of a rebound with a
    coefficient of restitution \f$e\f$. The relative velocity of the particle
    with respect to the mean value is used to calculate the direction and
    magnitude of the limited velocity.
