| Abstract: | With absorbing the thoughts of characteristic method for solving the hyperbolic equation and seeking exact solution of linearized equation in local element ,a characteristic hybrid finite analytic method is proposed to solve convection diffusion equation .The theoretic analysis and numerical examples indicate that the properties of this scheme are very good,and it is more fit for calculating the problem while convection is dominant. |
