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