I am still getting the same error (still library error).
In your system, If you didn't get any error, please kindly inform me your system environment sush as, os, version of visual studio, sdk etc..

it may relate platform problem? my system is win64.

No, it is not a platform problem. The reason is that

lround

is not implemented in MSVC's math.h file.

Add the line

#define lround(x) (int)((x)+0.5)

after

#include "udf.h"

and try again.

Sorry for the inconvenience.

Great. Thanks Blackmask!!.
Finally I forward one step.

I defined velocity inlet as udf u_profile::libudf after load your code.
then I simply run it but the assigned velocity is zero at inlet surface.

After loading code, I defiend velocity inlet as udf u_profile::libudf at boundary condition.
Then simply run it but assigned velocity is zero at the inlet surface.

um.....

Attached file is a very simple test domain which has same coordinate of the input data.
could you check it if you have time?

Thanks in advance

You can not count everything on me. It is your job after all. The data file in the source code is "voutu.txt", as you mentioned in several posts before. The file name in the zip file is "voututen.dat". The input format specifier is

fscanf(fp, "%f,",...)

i.e., the data is separated by a comma, again, as you shown in some previous post. The data in the zip file is separated by space.

I am willing to help people and I understand that you want to make progress fast. But please spend sometime preparing yourself. It does not take long for you to understand the basics of c programming language.
