scipy_iter_solver.py

Define the scipy iterative solver class.

class openmdao.solvers.linear.scipy_iter_solver.ScipyIterativeSolver(*args, **kwargs)

Bases: openmdao.solvers.linear.scipy_iter_solver.ScipyKrylov

Deprecated. See ScipyKrylov.

SOLVER = 'LN: SCIPY'

__init__(self, *args, **kwargs)

Deprecated.

Parameters

*argslist of object

Positional args.

**kwargsdict

Named args.

add_recorder(self, recorder)

Add a recorder to the solver’s RecordingManager.

Parameters

recorder<CaseRecorder>

A recorder instance to be added to RecManager.

cleanup(self)

Clean up resources prior to exit.

property msginfo

Return info to prepend to messages.

Returns

str

Info to prepend to messages.

property preconditioner

Provide ‘preconditioner’ property for backwards compatibility.

Returns

LinearSolver

reference to the ‘precon’ property.

record_iteration(self, **kwargs)

Record an iteration of the current Solver.

Parameters

**kwargsdict

Keyword arguments (used for abs and rel error).

solve(self, vec_names, mode, rel_systems=None)

Run the solver.

Parameters

vec_names[str, …]

list of names of the right-hand-side vectors.

modestr

‘fwd’ or ‘rev’.

rel_systemsset of str

Names of systems relevant to the current solve.

class openmdao.solvers.linear.scipy_iter_solver.ScipyKrylov(**kwargs)

Bases: openmdao.solvers.solver.LinearSolver

The Krylov iterative solvers in scipy.sparse.linalg.

Attributes

precon

(Solver) Preconditioner for linear solve. Default is None for no preconditioner.
