The error says it can't read certain file in the installation directory.
Did you install ANSYS with 'run as admin' ?
Check the permissions on your installation directory and make sure your username at least has read permission.
A potential temporary workaround might be to run Fluent with 'run as admin' .
I'm pretty sure i installed with run as admin and that my username have admin privilege. I got the same results when i ran fluent with run as admin
Something is wrong with your permissions. Please uninstall this and manually remove D:\ANSYS Inc folder afterwards. Then re-install again, make sure you 'run as admin' and see if the issue persists.
I uninstalled and re downloaded ansys and it getting the same result
If you look at the console text output, this is now a different issue. It can now go farther but Fluent is still not completely launched , so the screen is still grey.
Try launching it with this mode
Processing Options : Parallel
Processes : 0
Does this help ?
Also, open CMD Prompt and issue this command
ping %computername% -4
and post the screenshot of the output of i
fluent opened fully when i ran it parallel. Here is the command prompt
When i try to run it in workbench it opens and then the second i try to do anything it fails
Can you elaborate on this 'fail' ?
Is there any error message ?
Does it crash ?
What if you specify
Processing Options : Parallel
Processes : 2
For both using processes: 0 or 2 i receive the same error each time:
fluent failed to start
Now, I'm confused.
What do you mean when you said "fluent opened fully when i ran it parallel."
From what I could tell it appeared as though fluent opened and fully loaded, but once i tried to do anything the program crashed.
If you launch stand-alone Fluent, do you have any issue (try both 0 and 2 processors) ?
Your issue with Workbench-Fluent is because of that error "unable to connect to external socket, error during socket creation" . This is likely because Firewall or Anti-virus software on the machine is blocking this.
Ok so It open and ran fine when i used o processors but i received this when I ran 2 processors
if the error on workbench is a problem with my firewall or anti-virus software, how would i fix that?
so there is no graphics-related issue here (which was one of the main culprits I was thinking about)
All of these issues are related to your Firewall or Anti-virus software. Just for a test, turn every security software on your machine off temporarily and see if it works. If it works, then turn them back on one-by-one and see which one is the one that causes the issue, then make sure you add ANSYS Inc folder to the 'exclusions' list of that software.
I have been having the same issue with ANSYS 19.2 and 2019 R2. I have turned off the anti-virus as well as the firewall. But I still get the issue which states "Unable to connect to external socket: Error during socket creation".
I would recommend to create a new thread for your own.
There is still something blocking socket connections. Are you on VPN ? Are you using any remote desktop visualization tool ?
Do you see the same error if you launch it in non-GUI mode, something like
"%awp_root194%\fluent\ntbin\win64\fluent.exe" -r19.4.0 3d -g
I read on another forum that this can be solved by trying you use the fluent stand-alone from the "Component Systems" and then importing the model/mesh from another study. I did that and this resolved the problem.
Since then, the application is finding looking up the correct license and is not giving me any issues. I don't know why this worked, but it seems to have resolved the issue for me.
That's very odd. Thank you for sharing the resolution.
