Thank you for explaining this great software. Does this also work for biplanes?

[@dr.gudmundssonaircraftdesign]

Excellent question: Yes. It works for any kind of configuration; symmetric or asymmetric, mono or multiplane. Simply does not "care" about where or how lifting surfaces are placed. Best wishes.
