FMU disciplines of the Sellar use case.
Use case proposed by Sellar et al. in
Sellar, R., Batill, S., & Renaud, J. (1996). Response surface based, concurrent subspace optimization for multidisciplinary system design. In 34th aerospace sciences meeting and exhibit (p. 714).
The MDO problem is written as follows:
where the coupling variables are
and
and where the general constraints are
This package implements three disciplines to compute the different coupling variables, constraints and objective:
FMUSellar1
: thisMDODiscipline
computes \(y_1\) from \(y_2\), \(x_{shared,1}\), \(x_{shared,2}\) and \(x_{local}\).FMUSellar2
: thisMDODiscipline
computes \(y_2\) from \(y_1\), \(x_{shared,1}\) and \(x_{shared,2}\).FMUSellarSystem
: thisMDODiscipline
computes both objective and constraints from \(y_1\), \(y_2\), \(x_{local}\) and \(x_{shared,2}\).
