      Hi Yiting,

      Check if you have the feature "lum_fdtd_gui" in your license file.

      If yes then, can you make entries in the host file: (You will require admin access)

      ·        Open the HOSTS file on the client machine and add the license server name and IP of the license server in that hosts file.

      ·        Path: “C:\Windows\System32\drivers\etc “ as per the following format in your client machine :


      IP address of server            Hostname of server                     FQDN                                                               //IP address of server and name. You can also add FQDN.


      ·        Add the below-mentioned line at the end of hosts file.


      ·        Once the entry is added save the file.

      ·        Launch the Ansys application.

      If you face any issues, send screenshot of it.
