Abstract

Multi-phase groundwater flow and transport problems can be solved accurately using the classical collocation method with Hermite cubic basis functions. However, because of inefficiencies inherent in the classical collocation method, the computational time required to solve large-scale problems limit its widespread use. However, when this complex model is modified to utilize a new numerical concept based upon a localized collocation formulation, the computational efficiency of the code is significantly enhanced. Solutions to the groundwater flow and transport equations obtained using the classical and new formulation were compared for accuracy as well as efficiency. An increase in speed of more than 100 percent has been observed for large problems. © 2002 Elsevier B.V. All rights reserved.
