splitter module¶

A discipline splitting an input variable.

class gemseo.disciplines.splitter.Splitter(input_name, output_names_to_input_indices)[source]

Bases: MDODiscipline

A discipline splitting an input variable.

Several output variables containing slice of the input variable are extracted.

Examples

>>> discipline = Splitter("alpha", {"beta": [0, 1], "delta": [2, 3],
"gamma": 4})
>>> discipline.execute({"alpha": array([1.0, 2.0, 3.0, 4.0, 5.0])})
>>> delta = discipline.local_data["delta"]  # delta = array([3.0, 4.0])

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

Parameters:

input_name (str) – The name of the input to split.
output_names_to_input_indices (dict[str, Iterable[int] | int]) – The input indices associated with the output names.

cache: BaseCache | 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.
