二完整的 3D 稳定的数学模型被有限元素方法开发(女性) 联合了物理地计算：电磁的模型首先并且那么被造并且解决作为在海军司烧方程的来源身体力量是有获得的电磁的力量的液体运动模型。铁磁性的壳，总线工具条系统在附近，和导致的电流以磁场被考虑的开的边界问题以及里面引起的效果。而且，一个新建模方法被发现建立稳固的模型然后协调他们完全与所谓的把结构化的格子，也就是十六进制网孔。有二种公共汽车酒吧安排的 75kA prebaked 房间的例子被举。结果同意在文学揭示的那些并且证实联合模拟是有效的。这些模型的用法便于电场的一致分析到磁场然后流动运动到更大的程度，电流密度的本地分布和磁性的流动密度，这也被结束非常依赖于房间结构，钢壳是盾减少磁场，流动模式是二在金属垫的主要身体维。

英文摘要：

Two full 3D steady mathematical models are developed by finite element method （FEM） to calcalate coupled physics fields. the electro-magnetic model is built and solved first and so is the fluid motion model with the acquired electromagnetic force as source body forces in Navier-Stokes equations. Effects caused by the ferromagnetic shell, busbar system around, and open boundary problem as well as inside induced current were considered in terms of the magnetic field. Furthermore, a new modeling method is found to set up solid models and then mesh them entirely with so-called structuralized grids, namely hex-mesh. Examples of 75kA prebaked cell with two kinds of busbar arrangements are presented. Results agree with those disclosed in the literature and confirm that the coupled simulation is valid. It is also concluded that the usage of these models facilitates the consistent analysis of the electric field to magnetic field and then flow motion to the greater extent, local distributions of current density and magnetic flux density are very much dependent on the cell structure, the steel shell is a shield to reduce the magnetic field and flow pattern is two dimensional in the main body of the metal pad.
