Dear all,

i hope you are well! I am running ANSYS v15.0 on Ubuntu 12.04LTS (which i know is an 'uncertified distro') and receive the following message when i load a parallel case into Fluent:

Code:
Setting process affinity: failed opening libc!
I know that this is obviously an error with Fluent not being able to call the appropriate function in the C-standard library to set the process affinity for the job, but i know libc is installed on the machine, so i was wondering whether anyone else had had an issue like this? I havent been able to find much (anything ) on the forums apart from someone else who had the same issue and asked but got no response!

I also run ANSYS v15.0 on another Ubuntu machine without this issue, so i am a little stumped.

Any help would be much appreciated, as i think not have process affinity adversely affects my simulations who badly, since the threads jump around a lot!

thanks and best regards
jonathan

Fixed by adding symlink to libc.so.6:
