Detailed Description

template<class DFImp, class Operator>
class Dune::Fem::DiagonalPreconditioner< DFImp, Operator >

Precondtioner, multiplies with inverse of the diagonal works with.

• OEM
• ISTL (choose jacobi, iteration = 1)

Parameters

DFImp	type of the disctete function
Operator	type of the operator (only works for assembled operators)

Member Function Documentation

finalize()

virtual void Dune::Fem::Operator< DFImp , DFImp >::finalize ( )

inlinevirtualinherited

finalization of operator

Note

The default implementation is empty.

nonlinear()

virtual bool Dune::Fem::Operator< DFImp , DFImp >::nonlinear ( ) const

inlinevirtualinherited

Return true if the Operator is nonlinear and false otherwise (default is true).
