After searching for site-wide configuration files, Ansys CFX looks for the following user’s configuration files:
cfx5rc-<host>.txt
cfx5rc-<arch>.txt
cfx5rc-<os>.txt
cfx5rc.txt
(and for the same files without .txt appended) in the following directories:
On Windows: %USERPROFILE%\Application Data\CFX-5\24.2\ if it exists, otherwise %HOMEDRIVE%\%HOMEPATH%\.cfx\24.2\ where %USERPROFILE%, %HOMEDRIVE% and %HOMEPATH% are environment variables.
On Linux: ~/.cfx/24.2/ and ~/CFX/24.2/
where ~ means your home directory (if you have one).
