A radial slit domain is the entire plane with slits along rectilinear lines pointing at the origin. In this paper, we present a simple numerical method for computing conformal maps from domains exterior to closed Jordan curves onto the radial slit domain. The mapping is important in problems of two-dimensional point-source flow with obstacles. The numerical method is based on the charge simulation method, in which conjugate harmonic functions are approximated by a linear combination of complex logarithmic potentials. It is shown that the method works well for some typical domains.
