摘要
利用有限差分求解了二维稳态对流-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是可行的、有效的。
In this paper,two-dimensional variable coefficient ellipse 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 numerical results show that this method is feasible and efficient.
