UDF problems - velocity profile

Oli

Hi everybody.

I'm trying to create a non uniform velocity profile at inlet ; the same as you can find it in the Fluent Docs.

The source code is

#include "udf.h"

DEFINE_PROFILE(x_velocity,thread,index)

{

real x[ND_ND];

real y;

face_t f;

begin_f_loop(f,thread)

{

F_CENTROID(x,f,thread);

y = x[1];

F_PROFILE(f,thread,index) = 30.0-30.0*(y*y)/(1.5*1.5)

}

end_f_loop(f,thread)

}

now i try to compile the source code

--> Define --> User Defined Functions --> Interpreted (as it is shown in the Fluent Docu)

But I always get the error : Error: /.../... : line 2 : syntax Error

Do i overlook something?
