The superblock approach for the analytic element method

An approach, the superblock approach, is presented for increasing computati onal efficiency of analytic element models. The approach is based on comput ing the combined effect of functions using both asymptotic expansions and T aylor Series expansions. The superblocks are used to reduce both the comput ational effort required to determine the coefficients in the analytic eleme nt model and to reduce the effort expended in generating contour plots and streamlines. An application of flow is presented in an aquifer with one hun dred thousand circular impermeable objects. The errors in the simulation ar e within the machine accuracy.
