lum_fdtd_gui missing

    • Vicente Fito

      I am trying to run the example script for ring_modulator_time_domain_validation, and the following error pops up:

      Error: failed to checkout feature 'lum_fdtd_gui' Request name lum_fdtd_gui does not exist in the licensing pool. No such feature exists.


      License path: 1055@localhost;

      FlexNet Licensing error: -5, 147

      Would you like to reconfigure your license settings?


      I understand that there is part of the license missing, I have an evaluation license, is there somewhere where I can find the mentioned feature, or a way to solve this error?


      Thank you very much,

      Vicente Fito

      Sorry to reply you late due to some circumstances.

      Is this issue resolved? 

      Do you mean this exmaple 

      All the files are for INTERCONNECT. no simulation needs FDTD.

      Please reboot your computer, and check the license as well as products included. Please let me know if the problem still exisits.

      Do you have an evaluation license or accessing your organization's license server? 
      Can you share the following? 
      * Screenshot of your license configuration >> How to obtain a floating license – Ansys Optics 
      * Screenshot of the Ansys License Manager > Display FlexNet license status >> Ansys license management center (overview) – Ansys Optics
      * Screenshot of the error message.

      @Lito - I got it sorted. Thanks a lot anyways. I believe it was something to do with the evaluation license.
