Dear All,

I try to compile a simple UDF which is involving an inlet velocity profile. But I get this common warning :

warning: no newline at end of file

It is explained in Fluent tutorial: "Another common error occurs when the argument list for a DEFINE statement is placed on multiple lines. (All DEFINE macro arguments must be listed on the same line in a C file.)"

My macro arguments are already on the same line (as seen below). Can anyone help me with this error?

with kind regards,

#include "udf.h"

DEFINE_PROFILE(axial_velocity,t,i)

{

real x[ND_ND];

real y;

face_t f;

begin_f_loop(f,t)

{

F_CENTROID(x,f,t);

y = x[0];

F_PROFILE(f,t,i) = 5.31*(1-(y/.05)*(y/.05));

}

end_f_loop(f,t)

}

I din't see any error while compiling your code. I used "compiled" udf option and load the library using manage option(define->user-defined->functions->compiled & load library). I am able to see as a profile in the boundary condition panel.

Thanks, mohan

i am not getting any mistake in your udf.

This is a common compiler error. You simply need to add one new empty line at the end of your .c source code file before saving it. Then it should work fine.
