Hi Junya,

  1. Clear the cache of the Fluent application by renaming the Ansys folder to Ansys.old (type in windows search bar %appdata% or C:\Users\username\AppData\Roaming\Ansys), rename .cfx and fluent.conf folder(C:/Users/username), relaunch the application to check if you can launch it successfully.
  2. Screenshot of the error if any?
  3. Is this issue occurring only for the CFD application, can you please check if you can successfully launch other Ansys applications too?
  4. When you launch fluent application (fluent utility) can you click on reset to default?
  5. Can you please check if any security software/ antivirus is blocking the Ansys CFD application?
  6. Can you please check if any av/security s/w is blocking it?

>> Launch the application then, Go to Start Menu àEvent Viewer àWindows logs àApplications. Check for Error in it, send screenshot if possible.
