Since I use some quantity of C_UDMI I shoul give them names for easier handling. I do it as in UDF Manual said:
the best way, accordingly, is to declare Set_User_Memory_Name in DEFINE_ON_LOADING macro.
It works when the project *.cas is loaded, the my UDF is compiled.
But then if close everything prior to that saving of course, I reload Fluent and my *.cas and then I receive memory error on loading and the UDM followa like taht: 0, 1, 2, ect. My prescribed names are vanished.

What is the problem? Shall Transfer my Set_User_Memory_Name from DEFINE_ON_LOADING to DEFINE_INIT?
