详细描述

template<int DIM, class value_type0, class value_type1 = value_type0, int DOW = DIM, int TDIM0 = DIM, int TDIM1 = DIM>
class BilinearOperator< DIM, value_type0, value_type1, DOW, TDIM0, TDIM1 >

class BilinearOperator is the discretized version of the bilinear form on two linear space

thus for and to be finite dimensional space with basis function as and , respectively, the bilinear form can be given as a matrix with its entry as

The linear finite dimensional spaces here are two finite element space and the resulted matrix is a sparse matrix. The method getElementMatrix is a pure virtual function that you must specify this method in derived class to contruct an object. Typical code to use this class is as:

 // definition of the derived class
 class a_bilinear_operator : 
   public BilinearOperator<DIM, double>
 {
   ... ...
   virtual void getElementMatrix(const Element<double,DIM>&,
                                 const Element<double,DIM>&);
   ... ...
 };

 a_bilinear_operator::getElementMatrix(const Element<double,DIM>&,
                                       const Element<double,DIM>&)
 {
   // implementation code of this bilinear operator
   ... ...
 };

 // use this bilinear operator
 void some_function()
 {
   ... ...
   a_bilinear_operator op(fem_space0, fem_space1);
   a_bilinear_operator.algebricAccuracy() = 3;
   a_bilinear_operator.build();
   ... ...
 };
