grating S-parameters

      Hello, I have a question regarding the display of results. I am using the grating S-parameters  for my 3D simulations with 2000 frequency points, and my frequency range is from 200 to 400 GHz.

      The simulation takes a few hours, but after it finishes, the display of the results (S-parameters) also takes a few hours. Is this normal? Do you know why this might be happening?

       

      Thank you in advance

      Hi Amina,

      Thank you for posting your question on the forum. The main issue here is the number of frequency points: the grating S-parameter analysis group calculates the S parameters at each frequency, sequentially (basically, using a for loop in the analysis script), so with 2000 points, the loop takes some time!

      The first question would be whether you need that many point? Is that the case?
