有关lumopt正向伴随仿真不收敛的问题

      尊敬的各位老师:

      首先来介绍一下我仿真的基本设置,自定义光源z轴负方向打进结构,进而转化成波导模式。频率3.4THz。波导和设计区域介质index=3.6,背景空气index=1。

      首先逆向设计需要进行一次forward仿真,在forward仿真中不收敛。

      https://innovationspace.ansys.com/forum/forums/topic/ansys-insight-fdtd-he-varfdtd-changjiandefasanyuanyinyijichuli/我看了这个帖子,将所有边界调整为metal,依然不收敛,我进一步缩减时间步长至0.5仍然不收敛。请问我下一步该如何调整?以下附上forward仿真的log,可以看出一直在1e-1量级震荡。

      感谢您的回复
