Class
    Foam::volBSplinesBase
 
Description
    Class constructing a number of volumetric B-Splines boxes,
    read from dynamicMeshDict. Useful for various sensitivities and
    optMeshMovement classes.
 
    Derives from MeshObject so that all instances know and update the same
    control points and parametric coordinates are computed only once
