"ineq_tolerance": 1e-5,
"eq_tolerance": 1e-3,
}
Create discipline¶
First, we create disciplines (aero, structure, mission) with dummy formulas
using the AnalyticDiscipline class.
aero_formulas = {
"drag": "0.1*((sweep/360)**2 + 200 + "
+ "thick_airfoils**2-thick_airfoils -4*displ)",
"forces": "10*sweep + 0.2*thick_airfoils-0.2*displ",
"lift": "(sweep + 0.2*thick_airfoils-2.*displ)/3000.",
}
aerodynamics = create_discipline(
"AnalyticDiscipline", name="Aerodynamics", expressions=aero_formulas
)
struc_formulas = {
"mass": "4000*(sweep/360)**3 + 200000 + " + "100*thick_panels +200.0*forces",
"reserve_fact": "-3*sweep " + "-6*thick_panels+0.1*forces+55",
"displ": "2*sweep + 3*thick_panels-2.*forces",
}
structure = create_discipline(
"AnalyticDiscipline", name="Structure", expressions=struc_formulas
)
mission_formulas = {"range": "8e11*lift/(mass*drag)"}
mission = create_discipline(
"AnalyticDiscipline", name="Mission", expressions=mission_formulas
)
disciplines = [aerodynamics, structure, mission]
We can see that structure and aerodynamics are strongly coupled:
generate_n2_plot(disciplines, save=False, show=True)
Create an MDO scenario with MDF formulation¶
Then, we create an MDO scenario based on the MDF formulation
design_space = AerostructureDesignSpace()
scenario = create_scenario(
disciplines=disciplines,
formulation="MDF",
objective_name="range",
design_space=design_space,
maximize_objective=True,
)
scenario.add_constraint("reserve_fact", "ineq", value=0.5)
scenario.add_constraint("lift", "eq", value=0.5)
scenario.execute({"algo": "NLOPT_SLSQP", "max_iter": 10, "algo_options": algo_options})
scenario.post_process("OptHistoryView", save=False, show=True)

Create an MDO scenario with bilevel formulation¶
Then, we create an MDO scenario based on the bilevel formulation
sub_scenario_options = {
"max_iter": 5,
"algo": "NLOPT_SLSQP",
"algo_options": algo_options,
}
design_space_ref = AerostructureDesignSpace()

self.__current_value[name] = array_value.astype(
Create the aeronautics sub-scenario¶
For this purpose, we create a first sub-scenario to maximize the range with respect to the thick airfoils, based on the aerodynamics discipline.
design_space_aero = deepcopy(design_space_ref).filter(["thick_airfoils"])
aero_scenario = create_scenario(
disciplines=[aerodynamics, mission],
formulation="DisciplinaryOpt",
objective_name="range",
design_space=design_space_aero,
maximize_objective=True,
)
aero_scenario.default_inputs = sub_scenario_options
Create the structure sub-scenario¶
We create a second sub-scenario to maximize the range with respect to the thick panels, based on the structure discipline.
design_space_struct = deepcopy(design_space_ref).filter(["thick_panels"])
struct_scenario = create_scenario(
disciplines=[structure, mission],
formulation="DisciplinaryOpt",
objective_name="range",
design_space=design_space_struct,
maximize_objective=True,
)
struct_scenario.default_inputs = sub_scenario_options
Create the system scenario¶
Lastly, we build a system scenario to maximize the range with respect to the sweep, which is a shared variable, based on the previous sub-scenarios.
design_space_system = deepcopy(design_space_ref).filter(["sweep"])
system_scenario = create_scenario(
disciplines=[aero_scenario, struct_scenario, mission],
