Observed dark plasma flows descending through the solar corona originated above posteruption flare arcades (refered as supra-arcades downflows) have been detected in X-ray and extreme-ultraviolet observations. We already demonstrated that these dark structures are consistent with descending plasma voids generated by the bouncing and interfering of shocks and expansion waves produced by initial localized depositions of energy. Results were obtained by means of 2D MHD simulations. Here we present ourfirst 3D MHD simulation approach to this phenomenon.
