This is my first time writing and using fluent udf in ANSYS. My code executed on a windows machine, but due to restricted license I had to switch to a linux workstation and my UDF stopped working.

Within ANSYS fluent v16.1, I got a syntax error when I tried to compile and interpret. I am not sure what the problem is; I might be missing something. I would appreciate any help, because this is holding up a very important project I need to complete for graduation. Below is my code:

#include "udf.h"

/*define constants*/

#define UMEAN 1.0
/*#define 0.0*/
#define Re 1
#define VISC 2/Re
#define Symmetry 180
#define Phi 0.0

/*pass in thread associated with boundary zone; the udf will need to do the looping over all faces*/

DEFINE_PROFILE(x_velocity, thread, index)
{
real r, theta, ulocal, y, x[3]; /*radius, theta, local velocity, x array for coordinates*/
face_t f; /*f is face thread index*/


begin_f_loop(f,thread)
{
F_CENTROID(x,f,thread);
y = x[1];

F_PROFILE(f, thread, index)= (-r*sin(theta)*UMEAN*sin(theta))+(cos(theta)*-UMEAN*cos(theta));

}
end_f_loop(f,thread)
}

DEFINE_PROFILE(y_velocity, thread, index)
{
real r, theta, ulocal, y, x[3]; /*radius, theta, local velocity, x array for coordinates*/
face_t f; /*f is face thread index*/


begin_f_loop(f,thread)
{
F_CENTROID(x,f,thread);
y = x[1];

F_PROFILE(f, thread, index)= (r*cos(theta)*cos(Phi)*UMEAN*sin(theta))+(sin(thet a)*cos(Phi)*-UMEAN*cos(theta));

}
end_f_loop(f,thread)
}

DEFINE_PROFILE(z_velocity, thread, index)
{
real r, theta, ulocal, y, x[3]; /*radius, theta, local velocity, x array for coordinates*/
face_t f; /*f is face thread index*/


begin_f_loop(f,thread)
{
F_CENTROID(x,f,thread);
y = x[1];

F_PROFILE(f, thread, index)= (r*cos(theta)*sin(Phi)*UMEAN*sin(theta))+(sin(thet a)*sin(Phi)*-UMEAN*cos(theta));

}
end_f_loop(f,thread)
}

What was the compilation error? Try removing all comments or replace them with the one-line comment syntax (I've had similar issues with Linux compilers):

// comment here

When I take care of the comments, I get this error on my DEFINE_PROFILE() line:

"error: expected constructor, destructor, or type conversion before '(' token"

Any ideas on how to deal with this one?

What is your updated code and have you identified at which line this error occurs?
