Observed dark plasma flows descending through the solar corona originated above flare arcades, also referred as supra-arcade downflows (SADs), have been detected in soft X-ray and extreme-ultraviolet observations. Our group proposed a theoretical scenario to explain the nature of SADs, which mainly states that magnetic reconnection burst can generate descending plasma  voids sustained by the bouncing and interfering of shock waves. We present our first 3D MHD simulation results in the framework of our model.
