When starting up, FLUENT looks in your home directory for an optional file called .fluent. If it finds the file, it loads it with the Scheme load function. This file can contain Scheme functions that customize the code's operation.
The .fluent file can also contain TUI commands that are executed via the Scheme function ti-menu-load-string. For example, if the .fluent file contains the following:
(ti-menu-load-string "file read-case test.cas")
then FLUENT will read in the case file test.cas. For more details about ti-menu-load-string, see Section 3.5.
