Detailed Description

template<class DomainFunction, class RangeFunction = DomainFunction, class LinearOperator = AutomaticDifferenceLinearOperator< DomainFunction, RangeFunction >>
class Dune::Fem::AutomaticDifferenceOperator< DomainFunction, RangeFunction, LinearOperator >

operator providing a Jacobian through automatic differentiation

Note

The Jacobian operator is an on-the-fly operator, i.e., it does not store a matrix but only implements the application.

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()

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

pure virtualinherited

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 >.
