// -------------------------------------------------------------------------
// ShpCrvD.h  -  This header file contains the definitions of the 
//               degenerated curved area shape in the 3-dimensional space.
// -------------------------------------------------------------------------
// Remarks:
//        This shape definition is used in free-form shell elements.
//        The main difference from the other shapes is that the geometry is
//        not solely defined by the nodal coordinates, but also by the
//        nodal vectors. See node class for definition of these vectors.
