Title: Implementation of a conjugate residual iteration in the KIVA computer program

We describe the incorporation of the ICE method to replace the acoustic-subcycling method in the KIVA computer program. The implicit equations of the ICE method are solved by a conjugate residual iteration procedure, and a short introduction to the conjugate residual method is given. It is shown by means of example calculations that the acoustic-subcycling method, as it is implemented in KIVA, has some deficiencies that are not shared by the ICE method. 10 refs., 4 figs.
