Unable to open File in Ansys Fluent

      Hello,


      when running Ansys Fluent locally on my workstation I am unable to click the button "File" on the top left. Therefore I am unable to load any mesh, cas or dat file at that stage.

      In the Fluent launcher I can load Case, Mesh etc but after starting Fluent with the loaded files I again can't access the File Button nor can I Check my Problem with the Check Button or Initialize/Start/etc my simulation.


      This occurs with different independent msh, cas and dat filed and with Fluent 2020R1, 2021R1 and R2.

      Please can you post a screen shot? If you click into the text interface and press Enter a few times what happens?

      Hi Rob thanks for your quick reply. Here is the screenshot. When I Press Enter in the TUI the possible TUI commands are listed.
      If I click General -> Mesh -> Scale/Check/Report Quality/Display/Units, none of the buttons react...

      FYI: I was able to open and edit the file on a different workstation. So I assume something is wrong with my local installation (I have already reinstalled Ansys a few times though).

      Do the options in the tree work? I've only ever seen this behaviour with low end graphics, and even then it's rare as Fluent's not that fussy.

      I can click all options/tabs from Domain to Design and their suboptions will show/open, altough not all suboptions in each of those tabs works...
      Graphics card shouldnt be the problem (RTX 4000). And the confusing thing is, that Fluent has worked fine last week.

      I can btw. also load cas-file combination etc with the TUI (file/read-case-data), but with the GUI via "File" it is not possible...

      So the solver is OK but the GUI got scrambled. Unless has a better idea try renaming the %appdata% file and check the graphics drivers. To confirm, clicking on File does nothing or File-Read Case does nothing?

      Ok I will try that thanks for the information.
      Clicking on File does nothing (same behaviour as if a button is greyed out).

      Over night I ran a simulation locally on my Workstation using TUI commands. Now in the morning after this simulation has finished, the GUI works just fine again. I haven't installed any new drivers yet nor have I changed any %appdata% file...
      I can't really explain/understand this behaviour but maybe this information is helpful to you.

      Sounds like the computer pixies have got bored and gone somewhere else..... If it happens again let us know, otherwise I'm not sure there is a "fix"! or have you got any ideas?

      I have the same exact issue with a quadro P5000 on 2020 R2 Fluent, nothing I've tried (including renaming %appdata%, reinstalling drivers, and reinstalling Fluent products) has fixed the problem.

      Does moving your Fluent Application from one screen to the other help? (Assuming you have a two screen setup)

      Yeah, looks like moving the application to the other screen fixes this issue, thanks !
