There are two commands needed. The first to compile the UDF: /define/user-defined/compiled-functions compile libudf yes sourcename.c "" And the second to load the library that was compiled in the previous step: /define/user-defined/compiled-funcitons load libudf Note that 'sourcename.c' is the name of your UDF file and the "" are two quotation marks in sequence (needed to terminate the string array input to Fluent).
