Hi, I'm trying to display only one message with Message0 but I always get the following error message: function "CX_Message0" not found. I get the same error whether I interpret or compile the udf.

Never came across this Message0 macro. what it does?

if you want to print the message only 1 message, you can add a if condition that matches your cell condition like the one above

if ((c%10000)==0)
Message("");

[`e`]

Message0 is a modification of Message which only executes on compute node-0 (and also runs in serial). For printing a message only once per compute node, you could use a flag which switches off after the first message is printed (see a similar example here).

What is your full source code of the user-defined function?

Thanks for the suggestions e and Bruno. My udf is very simple. In the end restarting Fluent did the trick, Message0 works, I don't know what was wrong before.
