NAME

ElmTensorProd1  -  definition  of 1st order tensor product finite
elements

INCLUDE

include "ElmDefs.h"

SYNTAX

 class ElmTensorProd1 : public ElmTensorProd
 {
 public:

   static real elmSideArea(int side, const Mat(real) coor, int nsd);
   static void normalVector(int side, const Mat(real) coor, Ptv(real)& normal,
                            int nsd);
   static void getLocalMidPoint(int side, Ptv(real)& coor, int nsd);


   ElmTensorProd1 (int nsd_)
     : ElmTensorProd (nsd_, 1) {}

  ~ElmTensorProd1 () {}

   CLASS_INFO
 };

KEYWORDS

finite element, tensor product element, Lagrange element  family,
first order element

DESCRIPTION

The  class  is derived from class ElmTensorProd and restricts the
interpolation to be of order one (linear, bilinear,  trilinear,..
elements).   Elements  in an arbitrary number of space dimensions
are provided.

Most of the operations on this element type are  defined  through
virtual  functions  or member functions of the base class ElmDef.
See the documentation of class ElmDef for further explanation  of
the interface.

CONSTRUCTORS AND INITIALIZATION

The only constructor performs all the initialization.
