The X31 is an experimental aircraft developed to test ultra-high maneuverability via the use of thrust vectoring. The aircraft is a supersonic aircraft with canards instead of a horizontal tail to control the pitch of the aircraft. The geometry modeled includes the wings, fuselage, tail, canards, engine inlet and the engine outlet. A hybrid mesh was created using CENTAUR with prisms in the boundary layer and tetrahedra away from the aircraft.
