mdo_chain module

Some chains of SSBJ disciplines.

class gemseo.problems.sobieski.process.mdo_chain.SobieskiChain(dtype=DataType.FLOAT)

Bases: MDOChain

Chain the disciplines of the Sobieski’s SSBJ use case.

Order: structure, aerodynamics, propulsion and mission.

Initialize self. See help(type(self)) for accurate signature.

Parameters:

dtype (SobieskiBase.DataType) –

The NumPy type for data arrays, either “float64” or “complex128”.

By default it is set to “float64”.

cache: AbstractCache | None

The cache containing one or several executions of the discipline according to the cache policy.

data_processor: DataProcessor

A tool to pre- and post-process discipline data.

exec_for_lin: bool

Whether the last execution was due to a linearization.

input_grammar: BaseGrammar

The input grammar.

jac: MutableMapping[str, MutableMapping[str, ndarray | csr_array | JacobianOperator]]

The Jacobians of the outputs wrt inputs.

The structure is {output: {input: matrix}}.

name: str

The name of the discipline.

output_grammar: BaseGrammar

The output grammar.

re_exec_policy: ReExecutionPolicy

The policy to re-execute the same discipline.

residual_variables: dict[str, str]

The output variables mapping to their inputs, to be considered as residuals; they shall be equal to zero.

run_solves_residuals: bool

Whether the run method shall solve the residuals.
