Analysis0¶

Source: userfiles/Sellar/subsystem0/Analysis0.py

Analysis module for Sellar subsystem 0.

Implements the disciplinary analysis for the first subsystem in the Sellar multidisciplinary design problem, computing response variables from design variables and coupling variables.

Classes¶

Analysis0¶

Inherits from: AnalysisInterface

Analysis class for Sellar subsystem 0.

Computes the physical responses y1 and related quantities for the first discipline using the Sellar equations.

Attributes:

None specific to this class; inherits from AnalysisInterface.

Methods¶

init(self) → None

Initialize Analysis0 instance.

evaluateLocalResponses(self, subsystem: LocalSubSystemBasis) → None

Evaluate subsystem responses using Sellar discipline 1 equations.

Computes y1 and related physical responses from the design variables and coupling variables using the Sellar problem formulation.

Args:

subsystem: The local subsystem containing design variables and scalers.

mapLocalResponsesDesignVariables_to_CouplingParameters(self, subsystem: LocalSubSystemBasis) → None

Map subsystem responses to neighboring subsystems.

Transforms y1 to scaled values and distributes coupling variables y2 and shared design variables z1, z2 to subsystem 1.

Args:

subsystem: The local subsystem containing responses and scalers.

mapLocalResponsesDesignVariables_to_CouplingParameters_Jacobians(self, subsystem: LocalSubSystemBasis) → None

Map the Jacobians of the mapped responses.

Args:

subsystem: The subsystem for which the Jacobians are mapped.

mapLocalResponsesDesignVariables_to_CouplingParameters_Hessian(self, subsystem: LocalSubSystemBasis) → List[List[List[List[float | None]]]] | None

Map the Hessians of the mapped responses, if known a priori.

Args:

subsystem: The subsystem for which the Hessians are mapped.

Returns:

The mapped-response Hessian tensor
[coupling][mapped_response][n_dv][n_dv], or None for finite differences.
