| 摘 要： | 运动导体中电磁场控制方程为一对流扩散型微分方程,为克服此类方程的Galerkin有限元解在网格Peclet数大于1时出现的伪振荡同时克服Heinrich迎风有限元法对扩散项处理的不合理性,提出了一种修正的Heinrich迎风有限元法,并应用于若干运动导体电磁场的有限元分析。

| Abstract: | The governing equation of electromagnetic field in moving conductor is of convective-diffusive type. To suppress the spurious oscillations which occur in its Galerkin FEM solution when the grid Peclet number is greater than one and to avoid an inappropriate treatment of diffusive term by Heinrich's upwind scheme, a modified upwind scheme of Heinrich's type is proposed. The scheme is applied to FEM analysis of several electromagnetic field problems in moving conductor. |
