FLUENT doesn't start

Hello,

unfortunately I have a problem with starting the software FLUENT.

I also made a screenshot of the messages occurring in the Fluent console:


I have already tried the following things:

-) updated Windows 10

-) updated 15 drivers

-) deactivated firewall and antivirus software

-) deinstalled and reinstalled ANSYS

 

But unfortunately the problem persists, and FLUENT doesn't start.

I have only installed ANSYS student software, Version 2019 R3.

Maybe you can help me!

 

Best regards,

Franz

    Are you connected to a VPN? This issue is most often associated with a VPN connection, there is a trick in newer versions of Fluent (2019 R1 and newer) when encountering this issue with MPI. In Fluent Launcher, select Show More Options -> Parallel Settings -> MPI Type: msmpi , Select IP Interface 127.0.0.1. You may also try running while disconnected from the VPN.

    The licence for 2019R3 expired in August, what happens if you install 2020R2, or follow the instructions to update the licence?

  • @Rob I have already updated the license - I even had to do this, because ANSYS as a whole didn't work anymore at the beginning of September. I would like to continue my ANSYS introduction course on edX with 2019 R3, but if there is no other solution, I will try with 2020 R2. Thank you!
