Here the wing was given a uniform translation motion along with symmetric roll oscillations about the wing centreline. This sort of motion can only happen in 3D, but it is interesting to see how the wake appears to be made up of the basic structure that appeared in the case of heave oscillations, but with the wake of the heave oscillations appearing on either side of the wing centreline with each half in anti-phase with the other. The wing surface is coloured by pressure coefficient (vertex averaged). Observe how the surface pressure alternates over each half of the wing during the motion.
