Class
    Foam::lumpedPointDisplacementPointPatchVectorField
 
Description
    This is the point-patch responsible for managing the force
    integration on a 'lumped-point' basis, waiting for the external
    application, reading back the response from the external program
    and updating the locations of the associated patch points
    accordingly.
 
    The internal patch type name is 'lumpedPointDisplacement'.
 
    \heading Patch usage
    Example:
    \verbatim
    walls
    {
        type    lumpedPointDisplacement;
        value   uniform (0 0 0);
        controllers ( controllerName1 controllerName2 );
    }
    \endverbatim
