Inverse Design of Grating Coupler 2D/3D Question
I am trying to run the Inverse design of grating coupler 3D (https://support.lumerical.com/hc/en-us/articles/1500000306621-Inverse-design-of-grating-coupler-3D-) from my results from the inverse design of grating coupler 2D (https://support.lumerical.com/hc/en-us/articles/360042800573-Inverse-design-of-grating-coupler-2D-) and I am a bit confused as to the setup of the initial parameters. For my 2D model i created a geometry with 11 grating trenches. So the output file (pid_optim_final.json) would contain 22 entries for the starting point of the grating and the parameters for the polygons.
However i see for the 3D model it says this on the page:
So if i run my current output parameters from the 2D model it only draws 10 of the trenches, not 11. Do i need to add another entry to my 2D output (pid_optim_final.json) file to get it to draw all the trenches properly? If so, how can i amend the (pid_optim_final.json) file to add an entry?
