Returns
True/False: bool

True if RecordingManager is managing at least one recorder.

Call record_derivatives on all recorders.

Parameters
recording_requesterobject

The object that needs an iteration of itself recorded.

Dictionary containing derivatives keyed by ‘of,wrt’ to be recorded.

Metadata for iteration coordinate.

Call record_iteration on all recorders.

Parameters
recording_requesterobject

The object that needs an iteration of itself recorded.

Dictionary containing desvars, objectives, constraints, responses, and System vars.

Metadata for iteration coordinate.

shutdown()[source]

Shut down and remove all recorders.

startup(recording_requester, comm=None)[source]

Run startup on each recorder in the manager.

Parameters
recording_requesterobject

The object that needs an iteration of itself recorded.

commMPI.Comm or <FakeComm> or None

The communicator for recorders (should be the comm for the Problem).

openmdao.recorders.recording_manager.record_model_options(problem, run_number)[source]

Record the options for all systems and solvers in the model.

Parameters
problemProblem

The problem for which all its system and solver options are to be recorded.

run_numberint or None

Number indicating which run the metadata is associated with. Zero or None for the first run, 1 for the second, etc.

openmdao.recorders.recording_manager.record_viewer_data(problem)[source]

Record model viewer data for all recorders that have that option enabled.

We don’t want to collect the viewer data if it’s not needed though, so first we’ll find all recorders that need the data (if any) and then record it for those recorders.

Parameters
problemProblem

The problem for which model viewer data is to be recorded.
