An appealing feature of the well-known PIC algorithm for plasma simulations is the intuitive connection of the plasma representation with real plasmas. Working directly with macro particles'' provides intuition about plasma behavior but at greater computational expense for the extra detail that the method provides. Further, traditional explicit fully electromagnetic PIC algorithms still have stability and accuracy constraints that demand microscopic details be resolved in time and space. Recent progress in making the PIC algorithm implicit have been successful in allowing selective resolution in space and time of only those plasma phenomena of interest. We present here an overview of one of these procedures known as the direct implicit method as implemented in the LLNL code AVANTI. 6 refs.
