关于逆设计拓扑优化中初始结构的设置问题

      拓扑优化中可以用自定义的几何结构作为优化的起始结构,我参考了案例 “y_splitter_topology” 和 “CWDM_splitter_1310_4ch_2D_TE_topology” 中的设置:

      1. 将自定义的初始结构放入名为 “initial_guess” 的结构组中
      2. geometry 的 params 参数设置为None

      但是实际运行的时候会报错:UserWarning: Project file structure 'initial_guess' reports 1 parameters where expected 5929. This can occur when the number of x, y coordinates specificed to LumOpt do not match the dimensions of the FDTD grid. Try using similar or divisible delta values (size of a pixel) across all the axes.

      我FDTD的 mesh accuracy=3,待优化区域没有额外加网格,感觉和案例设置的一样,实在不知道为什么会报错,还有什么细节没有注意到吗?

      这个并不是报错,只是给出警告而已,警告的原因和修改方法。

      不修改问题也不大。
