User Error message with University license



I was pointed here by Ansys tech support. I am not sure why as it seems this is for Students Free version and not the paid version our University uses, but here goes.


I have a user who is getting this error "




Failover feature 'ANSYS Academic Research Mechanical and CFD' specified in licen

se preferences is not available.

Request name aa_r does not exist in the licensing pool.

License server system does not support this feature.

Feature:       aa_r

License path:  (Path to license server deleted for security)

FlexNet Licensing error:-18,147

For further information, refer to the FlexNet Licensing documentation,

available at "".

 *** ERROR - ANSYS license not available.


This is on CentOS. The user did use an academic research license, but I moved him over to our standard classroom license server and Ansys works. But Ansys APDL is not working for him. The shortcut I created for him points to the correct License server.

Everything I read online only talks about Windows version of Ansys. Are there any files I am missing in his profile that need to be changed or deleted to fix this error?

Thank you,

    On the client machine (the user's machine) , ask him to reset license preferences

    Windows : Rename %AppData%\Ansys\v1xx

    Linux : Rename $HOME/.ansys/v1xx
