UDF Error with udf_names.c

Hi,

I'm quite new to udf. Please be nice if this question is too easy for most of you.

I always get the following error message when I am trying to compile my udf on my Windows computer. Does anyone know what it means and how to solve this error? Thank you in advance.

udf_names.c(15) : warning C4113: 'void (*)()' differs in parameter lists from 'void (*)(void)'

It is not your mistake. Fluent gives slightly wrong instructions to the compiler. The compiler can guess what Fluent really means, so it does not have any effect on your simulation.

You can safely ignore this warning.

If you really don't want this warning text to be shown anymore: contact Ansys, and tell them to fix it. (I did not check yet if this is already fixed in Fluent 17.)

But in general, it is very good of you to look at all the warnings/errors you get when you compile, and it is a wise goal to write your code so that you don't see any more warnings. If this is the only warning you see, you did a better job than the Fluent programmers.
