NAME
       form_element - bilinear form on a single element


SYNOPSYS
       The  form_element  class defines functions that compute a bilinear form
       defined between two polynomial basis on a single  geometrical  element.
       This bilinear form is represented by a matrix.

       The  bilinear form is designated by a string, e.g. "mass", "grad_grad",
       ...  indicating the form. The form  depends  also  of  the  geometrical
       element: triangle, square, tetrahedron (see .  geo_element internal}').


IMPLEMENTATION NOTE
       The form_element class is managed by (see .  smart_pointer internal}').
       This class uses a pointer on  a  pure  virtual  class  form_element_rep
       while  the  effective  code  refers  to  the  specific concrete derived
       classes: mass, grad_grad, etc.


IMPLEMENTATION
       class form_element : public smart_pointer<form_element_rep> {
       public:

       // typedefs:

           typedef size_t size_type;

       // allocators:

           form_element (std::string name = "");

       // modifier:

           void initialize (const space& X, const space& Y) const;

           //  optional, for scalar-weighted forms:
           void set_weight (const field& wh) const;

               //  for special forms for which coordinate-system specific weights (ie, cylindrical
               //  coordinates weights) should not be used:
               void set_use_coordinate_system_weight(bool use) const;

       // accessor:

           void operator() (const geo_element& K, ublas::matrix<Float>& m) const;
           const field& get_weight() const;
       };
