S1-streamsurface computation: MISES

Our S1-streamsurface projection and adjoint steps are based on the cascade solver MISES, which has been developed by Mark Drela and Harold Youngren at MIT.

MISES assembles and solves a coupled system of Q3D freestream Euler equations with Coriolis- and centripetal forces

and integral Q3D-boundary-layer equations

The coupling is performed via displacement thickness and freestream velocity where direct coupling has been made possible by means of a q3D conservative streamtube curvature discretization of the Euler equations. Last, but by far not least there are some boundary conditions (inlet-outlet, Kutta, wall, wake ...).
