Simple disciplinary DOE example on the Sobieski SSBJ test case¶
from __future__ import annotations
from gemseo import configure_logger
from gemseo import create_discipline
from gemseo import create_scenario
from gemseo.problems.sobieski.core.design_space import SobieskiDesignSpace
configure_logger()
<RootLogger root (INFO)>
Instantiate the discipline¶
discipline = create_discipline("SobieskiMission")
Create the design space¶
design_space = SobieskiDesignSpace()
design_space.filter(["y_24", "y_34"])
Create the scenario¶
Build scenario which links the disciplines with the formulation and The DOE algorithm.
scenario = create_scenario(
[discipline],
"DisciplinaryOpt",
"y_4",
design_space,
maximize_objective=True,
scenario_type="DOE",
)
Execute the scenario¶
Here we use a latin hypercube sampling algorithm with 30 samples.
scenario.execute({"n_samples": 30, "algo": "lhs"})
