Hey all,

When I'm using the optimization function of SU2 to optimize a mesh model made by myself, I want to get the minimum value of LIFT.

I found SU2 seek the maximum value of LIFT by default?

Therefore, I wrote OPT_OBJECTIVE=LIFT*(-0.1), but it reported error.
Then I wrote OPT_OBJECTIVE=LIFT*-0.1, it seems work.

Is my operation correct? Is there document about discipline in detail of SU2 configuration file?

Yep OPT_OBJECTIVE=LIFT*-0.1 is correct. Anyway my recommendation is to take a look at the new SU2 v6 tutorial.

OPT_GRADIENT_FACTOR and OPT_RELAX_FACTOR are new important variables
