A grid was generated with the base of the fin, i.e. the hinge line, on the axis of a cylindrical domain with a diameter of 2m. Due to the axial symmetry of the setup, rotation of the T-tail should not change the pressure distribution on the T-tail. In reality, due to some a-symmetry in the grid, this was not quite achieved. The analyses consisted of a steady solution, followed by a prescribed, sine-squared, disturbance of 0.03 radians (corresponding to 10 mm lateral displacement at the fin top), followed by a coupled time-domain simulation.
