| 摘 要： | 提出了求解三维瞬态涡流场的一种新方法———全Ｈ棱边有限元边界元耦合法。即在涡流区以磁场强度Ｈ为求解变量用棱边有限元法离散，在非涡流区以Ｈ为求解变量用棱边边界元法离散，在这两个区域的交界面上进行耦合，充分发挥了有限元法和边界元法的各自优点。棱边元的应用使两种方法在交界面上的耦合显得很简单，最后用这种方法计算了ＴＥＡＭＷＯＲＫＳＨＯＰ问题７，计算结果符合实测情况。

| Abstract: | A novel total H edge element hybrid FEMBEM method is proposed for 3D transient eddy current problems in this paper.Finite element method is adopted in eddy current region,and boundary element method in eddy free region.Magnetic field intensity H is used as variable in both regions.This method gives full play to the advantages of both FEM and BEM.The use of edge elements makes the hybrid of these two methods very easy on their interface.An example is given to verify the validity of the method. |
