Class
    Foam::fvMeshMovers::interpolator
 
Description
    Interpolates pre-specified motion specified as a set of pointVectorFields.
 
    The motion can be provided either as a set of displacement or position
    fields and the entry \c displacement specified accordingly.
 
Usage
    Example:
    \verbatim
    mover   interpolator;
 
    interpolatorCoeffs
    {
        field               wantedDisplacement;
        displacement        yes;
        interpolationScheme linear;
    }
    \endverbatim
 
    This will scan the case for \c wantedDisplacement \c pointVectorFields in
    the time directories 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 in
    parallel using \c decomposePar to decompose the set of \c pointVectorFields
    provided.
