constraint = create_discipline(

Create the design space

design_space = create_design_space()
design_space.add_variable("x", 1, l_b=-1.5, u_b=1.5, value=1.5)

Create the MDO scenario

scenario.default_inputs = {"algo": "SLSQP", "max_iter": 10}

Create the scenario adapter

adapter = MDOScenarioAdapter(
    scenario, dv_names, ["obj", "cstr"], set_x0_before_opt=True
