基于自适应有限元法（ALE）的地下污染物运移模拟

Abstract

A multi-dimensional finite element method (GWADAPT) which utilizes local mesh adaptation is used to calculate groundwater flow and subsurface transport of contaminant in saturated and unsaturated conditions. The model uses simple modifications to increase computational speed and reduce storage, allowing the model to run on PCs and workstations. GWADAPT can be accessed from the web and downloaded to a file. A parallel version of the model runs on an SGI Origin 2000 computer.
