remapping module

A discipline whose inputs and outputs map to those of another.

class gemseo.disciplines.remapping.RemappingDiscipline(discipline, input_mapping, output_mapping)[source]

Bases: MDODiscipline

A discipline whose inputs and outputs map to those of another.

An input or output name mapping looks like {"new_x": "x", "new_y": ("y", components)} where the variable "new_x" corresponds to the original variable "x" and the variable "new_y" corresponds to some components of the original variable "y". components can be an integer i (the i-th component of y), a sequence of integers [i, j, k] (the i-th, j-th and k-th components of y) or an iterable of integers range(i, j+1) (from the i-th to the j-th components of y).

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

  • discipline (MDODiscipline) – The original discipline.

  • input_mapping (NameMapping) – The input names to the original input names.

  • output_mapping (NameMapping) – The output names to the original output names.


ValueError – When the original discipline has no default input values.

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.

property original_discipline: MDODiscipline

The original 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.
