Abstract

This work presents the development and testing of time integration schemes for the system of ordinary differential equations resulting from the Dual Reci- procity Boundary Element Method ( DRM/BEM ) for the transient diffusion and convection-diffusion equations. The article describes applications of two-level and three-level schemes and the numerical solutions are compared with available an- alytical solutions for different combinations of the time step numerical weighting factors. Also, a method is proposed based on the three-level scheme together with active polynomial Richardson extrapolation of the solution. This method is p
