Hi everyone,
I would like to know if it is possible to performed in SU2 an objective function that optimize a lift-to-drag ratio.If it is what is the name of configure option. Thanks, João Lourenço |

João,
look at the options at the bottom of the config_template.cfg file. you can use the option OPT_OBJECTIVE to define the objective for your optimisation. you can use the same options listed for either objective or constraints, e.g: Code:
% Available flow based objective functions or constraint functions % DRAG, LIFT, SIDEFORCE, EFFICIENCY, % FORCE_X, FORCE_Y, FORCE_Z, % MOMENT_X, MOMENT_Y, MOMENT_Z, % THRUST, TORQUE, FIGURE_OF_MERIT, % EQUIVALENT_AREA, NEARFIELD_PRESSURE, % TOTAL_HEATFLUX, MAXIMUM_HEATFLUX, % INVERSE_DESIGN_PRESSURE, INVERSE_DESIGN_HEATFLUX, % SURFACE_TOTAL_PRESSURE, SURFACE_MASSFLOW % SURFACE_STATIC_PRESSURE, SURFACE_MACH best wishes Tom |

Thanks for you help. Can you help me in one more thing? If I want to introduce a pitching moment constraint of Mz => -0.087, how I introduce that in SU2? I don't know the axis direction and moments in SU2 and this leave me crazy. Thanks for you attention, João Lourenço |
