Abstract:
A numerical technique of the target-region locating(TRL)solver in conjunction with the wave-front method is presented for the application of the finite element method(FEM)for 3-D electromagnetic computation.First, the principle of TRL technique is described.Then, the availability of TRL solver for non-linear application is particularly discussed demonstrating that this solver can be easily used while still remaining great efficiency.The implementation on how to apply this technique in FEM based on magnetic vector potential(MVP)is also introduced.Finally, a numerical example of 3-D magnetostatic modeling using the TRL solver and FEMLAB is given. It shows that a huge computer resource can be saved by employing the new solver.
提出了一种用于三维电磁场有限元分析的数值技术, 即与波阵法配合使用的目标区域定位(TRL)算子.首先对波阵法进行了分析, 然后对TRL算子原理进行了详细论述, 并讨论了TRL算子在非线性场合应用的可行性, 指出其仍能够适用并保持原来的高效率.还介绍了TRL算子在采用矢量磁位函数有限元公式中的实现.最后给出了一个三维静磁场建模的算例, 分别采用TRL算子和有限元软件FEMLAB.结果表明:与FEMLAB相比, TRL算子可以节省可观的计算机资源.
