Class
    Foam::uniformInterpolatedDisplacementPointPatchVectorField

Description
    Interpolates pre-specified motion.

    Motion specified as pointVectorFields.

Usage
    Example:
    \verbatim
    walls
    {
        type                uniformInterpolatedDisplacement;
        value               uniform (0 0 0);
        field               wantedDisplacement;
        interpolationScheme linear;
    }
    \endverbatim

    This will scan the case for \a wantedDisplacement pointVectorFields
    and interpolate those in time (using \c linear interpolation) to
    obtain the current displacement.
    The advantage of specifying displacement in this way is that it
    automatically works through decomposePar.
