| Abstract: | An alternating group explicit (AGE) scheme is constructed on the basis of Samarskii difference scheme for solving two dimensional convection diffusion equation. The AGE scheme is absolutely stable and is imbued with distinct parallelism.By way of numerical experiment, the numerical results are compared with three dimensional stereogram for the use of analytical solution. The results indicate that the method has a good stability and a higher computational accuracy. |
