newton.py

Define the NewtonSolver class.

class openmdao.solvers.nonlinear.newton.NewtonSolver(**kwargs)

Bases: NonlinearSolver

Newton solver.

The default linear solver is the linear_solver in the containing system.

Parameters:

**kwargsdict

Options dictionary.

Attributes:

linear_solverLinearSolver

Linear solver to use to find the Newton search direction. The default is the parent system’s linear solver.

_linesearchNonlinearSolver

Line search algorithm. Default is None for no line search.

Methods

add_recorder(recorder)	Add a recorder to the solver's RecordingManager.
can_solve_cycle()	Return True if this solver can solve groups with cycles.
check_config(logger)	Perform optional error checks.
cleanup()	Clean up resources prior to exit.
get_outputs_dir(*subdirs[, mkdir])	Get the path under which all output files of this solver are to be placed.
get_reports_dir()	Get the path to the directory where the report files should go.
record_iteration(**kwargs)	Record an iteration of the current Solver.
report_failure(msg)	Report a failure that has occurred.
solve()	Run the solver.
use_relevance()	Return True if relevance should be active.

SOLVER = 'NL: Newton'

__init__(**kwargs)

Initialize all attributes.

cleanup()

Clean up resources prior to exit.

use_relevance()

Return True if relevance should be active.

Returns:

bool

True if relevance should be active.
