int RestartNonlinearProblemDiff::jacobian ( Vector< double > &  dst,
const Vector< double > &  src_yy,
const Vector< double > &  src 
)
virtual

Jacobian vector product for newton solver.

Reimplemented from NewtonArgument.

Definition at line 91 of file restart_nonlinear_problem_diff.cc.

int RestartNonlinearProblemDiff::jacobian_prec ( Vector< double > &  dst,
const Vector< double > &  src_yy,
const Vector< double > &  src 
)
virtual

Jacobian inverse preconditioner vector product for newton solver.

Inverse preconditioner vector product for newton solver.

Reimplemented from NewtonArgument.

Definition at line 193 of file restart_nonlinear_problem_diff.cc.

int RestartNonlinearProblemDiff::jacobian_prec_prod ( Vector< double > &  dst,
const Vector< double > &  src_yy,
const Vector< double > &  src 
)
virtual

Jacobian preconditioner vector product for newton solver.

Preconditioner vector product for newton solver.

Reimplemented from NewtonArgument.

Definition at line 206 of file restart_nonlinear_problem_diff.cc.

unsigned int RestartNonlinearProblemDiff::n_dofs ( ) const
virtual

Returns the number of degrees of freedom.

Pure virtual function.

Implements NewtonArgument.

Definition at line 3 of file restart_nonlinear_problem_diff.cc.

void RestartNonlinearProblemDiff::output_step ( Vector< double > &  solution,
const unsigned int  step_number 
)
virtual

This function is called at the end of each iteration step for the newton solver.

Once again, the conversion between pointers and other forms of vectors need to be done inside the inheriting class.

Implements NewtonArgument.

Definition at line 11 of file restart_nonlinear_problem_diff.cc.

int RestartNonlinearProblemDiff::residual ( Vector< double > &  dst,
const Vector< double > &  src_yy 
)
virtual

For newton solver, we need a residual function.

This one is computed with sacado to allow computations of derivatives for jacobian

Implements NewtonArgument.

Definition at line 20 of file restart_nonlinear_problem_diff.cc.

int RestartNonlinearProblemDiff::setup_jacobian_prec ( const Vector< double > &  src_yy)
virtual

Setup Jacobian preconditioner for Newton.

Preconditioner is the jacobian itself, so this matrix has nothing to do.

Reimplemented from NewtonArgument.

Definition at line 216 of file restart_nonlinear_problem_diff.cc.
