| Abstract: | Based on combining of muhiple grids and pretreatment iterative method, this paper puts forward a very effective method of solnting two-dimensional parabolic equation initial-boundary value problem. Through clever constructing pretreatment iterative matrix, the number of iteration matrix condition is reduced significantly, the convergence speed is accelerated and the solution efficiency is improved. |
