Abstract

A coupled adaptive finite element-boundary element-particle transport model is used to calculate pollutant transport in the atmosphere boundary layer. Using an h-adaptive technique, the finite element module accurately simulates winds and species transport over any irregular surface. Using boundary elements and Lagrangian Particle Transport, dispersion trajectories from pollutant sources can be calculated from within buildings to venting into the atmosphere. The model combination is ideal for problems involving large-scale dimensions, but needing local, refined solutions near important surface locations. 1 Introduction A coupled adaptive finite element technique (FEM), boundary element method (BEM), and Lagrangian Particle Transport scheme
