newton_sp_metadata Derived Type

type, public, extends(abstract_metadata) :: newton_sp_metadata

Metadata for Newton-Krylov fixed-point iteration.

Components

Type	Visibility	Attributes		Name		Initial
logical,	public		::	converged	=	.false.	Convergence flag
integer,	public		::	eval_counter_record	=	0	System response evaluation counter: N.B.: For each of these evals the current residual and tolerance are recorded.
integer,	public		::	info	=	0	Copy of the information flag for completeness
logical,	public		::	input_is_fixed_point	=	.false.	Flag indicating lucky convergence (Newton is not run and no solution is computed)
integer,	public		::	n_iter	=	0	Iteration counter
real(kind=sp),	public,	dimension(:), allocatable	::	res			Residual history
real(kind=sp),	public,	dimension(:), allocatable	::	tol			Tolerance history
