摘要
提出用有限元法求微分方程数值解的各种边值及初值处理技巧与方法,使得微分方程的边值与初值问题得到统一,扩展了有限元法对微分方程边值与初值的适定范围,并结合MatLab进行求解实验,验证该技巧与方法可行性,教学上简洁清晰,对理解有限元法具有启发性.
The paper advanced a skill of the boundary and initial problems on Differential Equation＇s FEM,integrated the boundary and initial problems into a group,expanded the applied range of FEM.With the help of MatLab,experiments were conducted to verify the feasibility of the skill,which is helpful in understanding FEM.
