摘　　要：给出了用有限元和边界元相结合的方法计算方坯软接触结晶器内钢液电磁场分布的全过程 ,并对 4面体单元基础上的Whitney边元素 ,H 方程及边界积分方程的离散方法作了重点解释 .采用有限元和边界元相结合的方法来计算电磁场的分布可以大大减少计算工作量和计算时间 .自行开发了三维电磁场计算程序 。The whole process of the numerical simulation of electromagnetic field in the liquid steel inside the soft\|contacting billet mold is presented by FEM(Finite Element Method) and BEM(Boundary Element Method). Whitney edge element FEM based on tetrahedral elements, the discretization of H  equation and boundary integration equation is mainly explained. By connecting FEM and BEM, it needs less work and time to the calculate the electromagnetic field. Numerical simulation program of three\|dimensional electromagnetic field is exploited and the solution is proved to coincide with the fact. [
