It depends on which errors comes on your screen after you click "build". I can not look at your screen.

Please read carefully: NOT the error that you get after clicking "load". That one you have shown me already.

On the wider question of learning UDFs and compiling UDFs:
-- Look at the help files and the tutorials.
-- I recently made a list of the steps that you have to follow to compile a UDF: see The UDF library you are trying to load (libudf) is not compiled for 3D on the current. But if you have not read any help materials at all, then this list might not make any sense.
-- When you compile, scroll back up and see if there are any compilation errors. If there are, you need to fix them before running the libudf. If they refer to specific lines in your input code, go and look at those lines. If they do not refer to your input code, something is wrong with your compiler setup -- check out pakk's helpful post from 2016: How to solve UDF compilation problems in Fluent.

Surprisingly: yes, I can.

You get the error message:

'nmake' is not recognized as an internal or external command

(You don't see this literally because your computer is set to a language that does not use the Latin alphabet, and the Fluent TUI is not able to show the characters of your language, but trust me, it is there.)

This means that your compiler is not set up correctly. Currently, your UDF code is not the problem.

Solve this. Look for the error message on this forum to find out how, I am no expert on this.

I'm getting a parse error as well for my UDF file. I would really appreciate if anyone could help me with it.

UDF File:
#include "udf.h"
DEFINE_PROFILE(x_velocity_a,thread,nv)
{
float pos[3]; /* an array for the coordinates */
float y;
face_t f; /* f is a face thread index */
begin_f_loop(f, thread)
{
F_CENTROID(pos,f,thread);
y = pos[1];
F_PROFILE(f, thread, nv)
= 1.-(400.*y-1.)*(400.*y-1.);
}
end_f_loop(f, thread)
}


Error, when using Interpreted UDFs: ....... line 15: parse error.

Thank You!
