Application of H-Adaptation for Environmental Fluid Flow and Species Transport

Abstract

An adaptive finite element model has been developed for simulating environmental fluid flow and species transport. The model uses Petrov–Galerkin weighting for the advection terms, mass lumping, and a h-adapting scheme that refines and unrefines the mesh using velocity and species concentration gradients. The model is currently being used to calculate atmospheric wind fields over the Nevada Test Site, and to calculate groundwater transport in saturated or unsaturated porous media. The model runs on Pentium PCs and SGI workstations; a parallel version of the model runs on an SGI Origin 2000 computer
