Detailed Description

template<class JacobianOperator>
class Dune::Fem::DifferentiableOperator< JacobianOperator >

abstract differentiable operator

Differentiable operators are operators providing a linearization.

Template Parameters

JacobianOperator

type of linear operator describing the Jacobian (linearization) of this operator

Note

The types for the operator's domain and range function are derived from the JacobianOperator.

An interface class:

Member Function Documentation

finalize()

virtual void Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::finalize ( )

inlinevirtualinherited

finalization of operator

Note

The default implementation is empty.

jacobian()

template<class JacobianOperator >

virtual void Dune::Fem::DifferentiableOperator< JacobianOperator >::jacobian ( const DomainFunctionType &  u, JacobianOperatorType &  jOp  ) const

pure virtual

obtain linearization

Parameters

[in]	u	argument discrete function
[out]	jOp	destination Jacobian operator

Note

This method has to be implemented by all derived classes.

nonlinear()

virtual bool Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::nonlinear ( ) const

inlinevirtualinherited

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

operator()()

virtual void Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::operator() ( const DomainFunctionType &  u, RangeFunctionType &  w  ) const

pure virtualinherited

application operator

Parameters

[in]	u	argument discrete function
[out]	w	destination discrete function

Note

This method has to be implemented by all derived classes.

Implemented in EllipticOperator< JacobianOperator::DomainFunctionType, JacobianOperator::RangeFunctionType, Model >.
