Hello, I´m trying to interpret an UDF that changes the value of the roughness constant:

#include "udf.h"

DEFINE_PROFILE(Cs,t,i)

{
face_t f;
begin_f_loop(f,t)
{
F_PROFILE(f,t,i) = 4.22112;
}

end_f_loop(f,t)
}

I have the error: "line 2: parse error".
I´ve tried to interpret it from "Fluent.Inc/ntbin/ntx86" too and I have the same result.

Help me please!

P.S.: I think I have used the same UDF before and it worked.

I don't see any error in your code.
Depending upon your fluent version, Cs might be an internal variable/or function in fluent.
You could change it to something else and try.

I changed Cs, [DEFINE_PROFILE(XXX,t,i)], and still have the problem.

The line 2 is the line under #include "udf.h" and it´s a blank line.
If I insert another lines at the start of the UDF, the error always appears in the same line, under #include "udf.h".

Your code compiles in my machine. I am using a 64 bit linux compiler. Have you compiled other UDFs successfully? Your problem could be compiler related.

Thank you very much.
Yes, I have compiled other UDF´s in the same machine succesfully. The machine es a 64 bit linux too.
However, I´ve tried to compile this UDF in other machines and it doesn´t work.

I think I´m doing it well:

Fluent 3ddp
Define>User-Defined>Functions>Interpreted
I chose the UDF (browse) and click "Interpret"

In the 64 bit linux, at first I interpret the UDF and then I compile it.
