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?
