利用有限元法求解了二维对流扩散方程边值问题,得到了相应的误差分析,并进行了数值模拟.模拟结果表明:该方法求得的数值解有较高的精度和较快的运行速度.
In this paper,two-dimensional convection diffusion equation with boundary conditions is resolved by using the finite element method,concludes the corresponding error estimation and is carried on the numerical solution simulation.The simulation results show that the numerical solution obtained by this method have higher accuracy and faster speed.
