      How can I fix this? Even when I try to close it, it says 

      Error: eval: unassigned variable

      Error Object: rp-host?

      and won't close.

      I need to use Fluent because I have 2 weeks left for my final project, so please help me

      What launcher options did you pick?

        When I tried to open 'Setup' to set boundary conditions for my mesh through Workbench 2023 R1, Fluent just stopped like the pictures below. And when I tried opening Fluent 2023 R1 by running with administrator, I got the error message like the picture above.

        I used the methods shown in this link /forum/forums/topic/the-fluent-application-failed-to-validate-the-connection-what-to-do/

        , but it doesn't work.

      Can you try launching Fluent from the Start menu?

        Yes, this is the result.

      The date format looks to have broken, but not sure if that should cause a problem. What parallel/gpu options are picked in the launcher?

        I chose default, which are: 1 solver processes and 0 Solver GPGPUs per Machine.

      Can you try a new working directory, eg c:/test  or similar. The "W" character in the path doesn't look right, and I know even the regionalised versions of the code struggle with a few non-ASCII characters.

        Yes, this is the result.

      Try the following:

      Close all Fluent/Ansys Programs.

      Open Windows File Explorer and type in the following in the address line:

      %APPDATA%\Ansys

      This will take you to your APPDATA\Ansys directory.

      You should see a directory named:  v231    (Or version you are using)

      Rename that directory to v231.old

      Now try to run.

        Thank you both, I can use Fluent now.

        For students who might have the same problems in the future, I will write down rest of the error fixing progress.

        According to your instructions, I renamed the directory to v231.old.

        Then the error 'fl2310.exe- Entry Point Not Found' occured.

        The last reply by the Deakin University student in the link /forum/forums/topic/solution-to-procedure-entry-point-error-pow2o3/ helped me, which was renaming the file svml_dispmd.dll to svml_dispmd.old .

        And fortunately, I can use Fluent now.

        Again, I thank you both for your kind instructions. Have a good day, and I wish you luck.
