A new approach for calculating the dc current from multiple Andreev reflection (MAR) is proposed. By rewriting the dc current in terms of the probability current, the dc charge current may be determined by studying the flow of probability current in the energy space. The flow in energy space can be mapped onto wave propagation in a one dimensional potential barrier structure. Using this formulation, different n-particle contributions may be separated to the current.
