Multiple Lifting Surfaces
=========================

It's easily possible to simulate multiple lifting surfaces simultaneously in OpenAeroStruct.
The most straightforward example is a wing and a tail for a conventional airplane, as shown below, though OpenAeroStruct can handle any arbitrary collection of lifting surfaces.
Note that the moment coefficient is always normalized with respect to the MAC of the first surface in the list; therefore, the main lifting surface (i.e., wing) should always be the first entry in the list.
