3D sloshing in a prismatic tank under translational coupled surge-sway (X and Y axis) motions. The main dimensions are height HT = 0.54m, width WT = 0.84m and length LT = 0.72m. The filling ratio of 50% (HF = 0.27m). The periods of surge and sway excitations are Ts = 1.25s with amplitude motions of Ax = 0.0144m (0.02 x length) and Ay = 0.0168m (0.02 x width).
