// ShpQUA6B.h  -   this file contains methods for the 6-noded quadratic
//                 quadrilateral finite element shape. This element  is
//                 linear in local "s" direction.   "QUA6DB" means that
//                 this element gives good results when modelling  beam
//                 behavior.
