Reply To: Lumerical CHARGE) meaning of decreasing free charge

Hi Sungmin,

I am sorry about the late reply. I will have to speak to our CHARGE expert on this. He is on vacation currently and will be back at the start of next week. I will get back to you then. Also, I am wondering why you have the shadow lines. In my experience with FDTD, it happens when there are overlapping geometries. I believe the geometry here is pretty straightforward but I still want to double-check with you. Do you have any overlapping geometries? And if yes, are their mesh orders properly assigned?

Regards,
