UDF problem
 

I have overcome a problem for the UDF where i have write a simple C program as shown below:

#include "udf.h"

DEFINE_PROFILE(unsteady_velocity, thread, position) { face_t f; real t = CURRENT_TIME;

begin_f_loop(f, thread) { F_PROFILE(f, thread, position) = 15.+(5.*sin(351.9*t)); } end_f_loop(f, thread) }

However, it shows parse error at the 1st line, which i cannot solve the problem. Somebody can please help me??

Re: UDF problem
 

do you interpret or compile it?

I interpret it. i do follow the example from fluent tutorial and dont know why got parse error.

Re: UDF problem
 

if you use browse to identify the location of your file, you musn't do that. you have to do exactly like fluent example.

Re: UDF problem
 

Yeah, for instance...

If your UDF file is in the same directory as your case file and named "example.c", then type just "example.c" in the source file name, not the entire path of the location of the file as the manual suggests.

That should work.
