This study evaluates DynIDDES for a standard wind-tunnel fighter model at high angles of attack. Compared with RANS, DynIDDES improves the agreement of lift/drag with wind-tunnel data, captures asymmetric separation and vortex breakdown, and reveals enhanced vortex coherence and delayed onset of vortex breakdown during dynamic longitudinal maneuvers.
