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?

[Sabin An]

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 https://forum.ansys.com/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? 

[Sabin An]

Yes, this is the result.

[Rob]

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?

[Sabin An]

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

[Rob]

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. 

[Sabin An]

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 https://forum.ansys.com/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.
