Class
    Foam::pointMeshMovers::linearDisplacement
 
Description
    Mesh motion solver simple linear expansion and contraction of a mesh
    region defined by a motion axis and the extents of the motion.
 
    Example:
    \verbatim
        mover           pointMeshMover;
 
        libs            ("libfvMotionSolvers.so");
 
        pointMeshMover  linearDisplacement;
 
        axis            (0 1 0);
        xFixed          0.8;
        xMoving         0;
        displacement    table
        (
            (0 0)
            (4 0.7)
        );
    \endverbatim
 
    This mesh is compressed between \c xFixed and \c xMoving in the direction
    \c axis between time 0 and 4 with a maximum displacement of 0.7.
    The mesh beyond \c xFixed is fixed and beyond \c xMoving moves with maximum
    displacement.
