Research in groundwater mechanics is focused on regional modeling of groundwater flow and transport. Computer modeling in this area requires handling large unbounded domains, simulating the flow in the area of interest, and dealing with oddly shaped internal boundaries. A new numerical method, called the analytic element method, has been developed in an attempt to meet these criteria. The method is based on superposition of suitable analytic functions, and has been implemented in several computer programs, which have been applied successfully to numerous problems of regional flow.
The Analytic Element Method is described in detail on his website, where there is a demo version of SLAEM (Single Layer Analytic Element Model) available for download.
