Hi Anna, 

I am refering to the inverse design example: https://optics.ansys.com/hc/en-us/articles/360042800573-Inverse-Design-of-Grating-Coupler-2D

and the code "pid_grating_coupler_sweep_2D.py" in the second step. 

I am not able to follow how did the designer define the start and the end point of the sweep. I would like to determine the transmission over the entire length of the grating.Â
