仿真总体思路:首先使用CHARGE模块仿真了不同电压下的载流子分布情况,然后将载流子分布导入3D-FDTD进行光学仿真,进而计算不同电压下的有效折射率变化。
仿真背景:按照官方的调制器示例,调制器结构在光传输方向上完全一样时,使用MODE模块进行二维仿真就能得到有效折射率变化。但我设计的结构在光传输方向上不一样(按周期分布),所以只能通过3D-FDTD仿真相位在传输方向上的变化,进而计算有效折射率变化。为了使仿真结果更准确,所以我想尽量增长3D-FDTD的仿真长度。
仿真问题:当增加仿真周期,即仿真长度从2um增加到5um时,仿真都一切正常。但继续增加周期,仿真长度增加到7um时,就会报错,如下图所示。请问怎么解决呢?

错误原因是unable to write project file,也就是说仿真文件不能被保存在指定的路径目录里。因此,你可能需要更换一个路径目录,最好写到C盘了,D和E盘有时可能会出问题。也有可能文件太大?你查看一下。
