AB: The source surface method is used to compute the Chapman-Ferraro currents for an arbitrarily shaped magnetopause confining a number of large-scale current systems. The model caclulates the magnetic field within the specified boundary from a scalar potential expanded in a set of general basis functions. The normal component of the total magnetic field due to all current systems within the source surface is minimized by the least squares method. This method proves to be a flexible approach to handle irregular magnetopause shapes, such as those that may be produced under extreme solar wind driving conditions.
