2-D simulations have matched the Saturn z-pinch experimental data well. Predictions for PBFA-Z based upon Saturn simulations were well within the measured range of early experiments and experimental improvements have now reduced the perturbation level required for PBFA-Z simulations by about a factor of five from those of Saturn. The simulations of the PBFA-Z experiments have also shown the unusual feature of a short-wavelength instability growth phase, saturated after breaking through the plasma shell, followed by longer wavelength development. This effect seems to be responsible for the plasma shell remaining intact and the subsequent high quality of the radiation pulse. In this talk, we will present the results of modeling the experiments of the first year of PBFA-Z implosions. We will also include a discussion of the use of the simulations in understanding experimental results and in designing future experiments and related applications such as the ``dynamic hohlraum''.
