      Hello, I was trying to follow the tutorial: https://support.lumerical.com/hc/en-us/articles/360042800293-Ring-resonator-getting-started-Design-and-initial-simulationnBut when I want to add an eigenmode to calculate the group index, It is not possible to Calculate the modes and select the desired one from the mode list. Can you help me with that?nThanks n

      Hi, I am not sure which file you are referring. I opened the lms file, enable FDE, run calculate, I got the result as below:nnnFor fsp file, since it is for FDTD, you cannot directly add a FDE solver. Instead, you can open one port, then visualize or calculate modes like this:nHowever, Port mode is designed for FDTD simulation, not for mode analysis, so you cannot do frequency sweep. nPlease note that FDE uses finer mesh so the mode profile looks smoother.nnI hope this helps.n

      Hi! I was referring to the lms file. I enabled FDE, clicked run and then on the Eigenmsolver analysis I clicked Calculate Modes and nothing happened. I cannot see the mode list:nnI'm using the version 2021 R1.1

      I tested the same version and it works fine:nnOne thing you can do is to upgrade to the newest version. When you click calculate, do you see a flash of any window change, or completely no any action in the GUI?.If the problem persistent, please give us your computer os information.n
