The paper centers on studying several types of smoothing operators for high-frequency perturbations within LEGAK-2D complex as applied to multi-cell computations. A smoothing operator by the fourth-order differences with weighting factors is ordinary used within LEGAK-2D programs. This operator was modified with regard to all defects and entered into LEGAK-2D complex. The smoothing operators of physical viscosity type and Chen smoothing operator are also entered into this complex. The results of test computations using proposed smoothing operators are presented. The recommendations for their use are given.
