CST频域求解器讲解.doc

版主你好，我把中文写在前，英文在后，这样翻译方便校对，不知你的意见如何？我离开学校有一年了，英语退步很大，另外CST频域求解这一块我也不精通，翻译得不好，请指正。虽然我自己翻译完全，有些内在含义不是很能理解。请指正! 频域求解器(Frequency Domain Solver) 一．频域求解器预览（Frequency Domain Solver Overview） 假定场和激励是时谐相关的，麦克斯韦方程组可能转换到频域。场可以用与瞬态场相关的相量来描述，瞬时场是把相量和时间因子相乘然后取实部得到。 通用的频域求解器解决的是一次一个频率和在扫频过程中的一系列自适应选择的频率的问题。The general purpose Frequency Domain Solver solves the problem for a single frequency at a time, and for a number of adaptively chosen frequency samples in the course of a frequency sweep. 对每一个频率样本，线性方程系统可以通过迭代（例如共轭梯度）或者稀疏直接求解器解决。For each frequency sample, the linear equation system will be solved by an iterative (e.g., conjugate gradient) or sparse direct solver. 方程的解包含在给定频率下的场分布和S参数。The solution comprises the field distribution as well as the S-parameters at the given frequency. 频率取样可以用离散算法并行计算得出（包括提交单一细微的计算或者并行运行参数扫描和优化）。看在频域求解器的参数和下面的离散算法和自适应取样的部分。Frequency samples can be calculated in parallel using distributed computing (besides submitting a single remote calculation, or running parameter sweeps and optimizations in parallel), see the corresponding frame in the Frequency Domain Solver Parameters and the section distributed computing and adaptive sampling below. 对于模型几何结构的离散化，在求解器开始运行前六面体网格和四面体网格可以根据需求适当选择。For the discretization of the geometry, the hexahedral mesh as well as the tetrahedral mesh may be chosen on demand right before the solver start. 如果仅仅需要S参数，那么“快速S参数谐振” 求解器是很有趣的。If only S-parameters are required, then the Resonant: Fast S-Parameter solver is of interest. 这个求解器目前能处理无损结构、小介质损耗、波导和离散端口。This solver can currently handle loss-free structures, small dielectric losses, waveguide and discrete ports. 除开S参数，场监视器有意义，那么“S参数和场谐振”求解器可以代替主要目的求解器。If, in addition to the S-parameters, field monitors are of interest, then the Resonant: S-Parameter, fields solver may be used instead of the General Purpose solver. 这个求解器目前能处理无损结构、波导和离散端口。This solver can currently handle loss-free structures, waveguide and discrete ports. 对所有这些求解器，在S参数计算完成后很有可能有效计算出电磁场监视器。For a
