论文摘要
在使用FEM（有限元方法）进行电磁分析的同时，如果我们可以实现问题的潜在对称性质，则计算成本将大大降低。问题的对称性质可以从给定的物理负载和问题的边界条件中鉴定出来。但是，对于电磁分析中的电磁分析，实现对称边界条件并不是很直接。在目前的工作中，已经证明了在节点框架内潜在公式中对称边界条件的新型实施。该实施是在电磁谐波和瞬态分析中针对广泛的辐射和散射问题进行的。与现有配方相比，计算成本的显着降低。
While doing electromagnetic analysis using FEM (Finite element method), if we can implement the underlying symmetric nature of the problem, there will be significant reduction in the computational cost. Symmetric nature of the problem can be identified from the given physical loading and boundary conditions of the problem. But for electromagnetic analysis in potential formulation, it is not very straight forward to implement the symmetric boundary condition. In the present work, a novel implementation of symmetric boundary condition in potential formulation within nodal framework, has been demonstrated. The implementation has been carried out in both electromagnetic harmonic and transient analysis for a wide range of radiation and scattering problems. A significant reduction in computational cost is achieved as compared to the existing formulation.
