Standard-BEM solutions to two types of anisotropic-diffusion convection reaction equations with variable coefficients

摘要

Two versions of diffusion-convection-reaction equations for anisotropic functionally graded materials (FGMs) 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.
