摘要：

A global interpolation function based dual reciprocity BEM is used to solve Darcy's flow in heterogeneous media. The governing equation of porous media flow is transformed into a Poisson-type equation with modified boundary conditions. The polynomial series based global interpolation functions are found to be efficient and accurate in converting the domain integral resulting from the Poisson equation into a boundary one. Numerical results are compared with known exact solutions.
