Class
    Foam::timeVaryingMappedFixedValueFvPatchField

Group
    grpInletBoundaryConditions grpCoupledBoundaryConditions

Description
    This boundary conditions interpolates the values from a set of supplied
    points in space and time.

    Supplied data should be specified in constant/boundaryData/<patchname>/
      - points             : pointField of locations
      - <time>/<field> : field of values at time <time>

    The default mode of operation (mapMethod = planar) is to project
    the points onto a plane (constructed from the first three points) and
    construct a 2D triangulation and finds for the face centres the triangle it
    is in and the weights to the 3 vertices.

    The optional mapMethod nearest will avoid all projection and triangulation
    and just use the value at the nearest vertex.

    Values are interpolated linearly between times.
