Changing wavelength in parameter sweeping

      Hi guys

      I am following this instruction to analyse the mode in the silicon waveguide.Optimizing waveguide geometry for single-mode – Ansys Optics 
      I would like to modify it and see the n_eff at other wavelengths. However, even if I changed the wavelength at here:

      The wavelength will automatically change to 1.55um when I start the parameter-sweeping process. 

      May I ask how to fix this problem and let me simulate the modes for other wavelengths?

      Thank you so much!

      I tested without issue. You can add the following two script lines to your script file:

      setanalysis("wavelength",1.06e-6);

       

      runsweep;

       

      and test to see if it works.

       

       

      the waveguide width is 0.8um now.
