Abstract
A least-squares mixed formulation is developed for simulation of two-p hase flow in porous media. Such problems anise in petroleum applicatio ns and ground-water flow. An adaptive strategy based on the element re sidual as an error indicator is developed in conjunction with unstruct ured remeshing and tested for the two-phase flow of oil and water. An element-by-element conjugate-gradient scheme (EBE-CG) is compared to a band solution algorithm.
