A boundary element method solution to spatially variable coefficients diffusion convection equation of anisotropic media

Abstract

The diffusion-convection equation with variable coefficients and for anisotropic media which were previously considered by other authors are discussed again in this paper to find their numerical solutions by using the boundary element method (BEM). The numerical results obtained show the consistency and accuracy of the BEM solutions. Also, the solutions exhibit the impact of the anisotropy and inhomogeneity (spatial variability) of the media.
