      I am simulating a grating for testing the reflection and transmission behavior.
      When I try to set DFT Spectrum – in the Simulation section this appears hidden.
      I am using the trial version for 30 days.
      Can someone help me ?

      Hello Giusy,

      The most likely explanation would be that your source is set to be Continuous-Wave (CW). If it is CW there is only one wavelength so the DFT spectrum option is not available. Can you confirm this is the case?
