This data is written to the temporary directory of your system, which is specified in the environment variable &#8220;TMP&#8221;. The temp-directory is usually set to  \/tmp  on Linux and to  C:UsersusernameAppDataLocalTemp  on Windows. To change the directory, you can either set the environment variable &#8220;TMP&#8221; to another directory permanently (this will also affect other programs including the operating system), or you can set &#8220;TMP&#8221; during the startup of Fluent in the Fluent launcher on the &#8220;Environment&#8221; tab. Simply type   TMP=D:mytmp  in the field &#8220;Other environment variables&#8221; to overwrite the value of &#8220;TMP&#8221; with, e.g., the directory D:mytmp just for this Fluent session.   Instead of using the Fluent launcher, you can also use the command line argument  -setenv=&#8221;TMP=D:mytmp&#8221;  when you start Fluent on the command line.  Please be aware that when you run Fluent inside Workbench, some data might also be written to the Workbench temporary directory.
