I tried getting the UDF define in C++. The real problem seems the inability of VS 13 to get the fluent related header file directly - as they are in C drive

I tried copying all headers .h file from C:\Program Files\ANSYS Inc\v150\fluent\fluent15.0.7\src and saved it local folder in home, but it shows error related to header files - so i think we cannot change header file from directory location
This bellow shows that the Visual studio is not getting the .h file file from fluent directory

he following is my code:

#include <stdafx.h>
//#include <iostream.h>
#include <C:\Program Files\ANSYS Inc\v150\fluent\fluent15.0.7\src\udf.h>
//#include <C:\winapps\FEniCS\lib\gcc\mingw32\4.6.1\include\s sp\stdio.h>
//#include <C:\winapps\FEniCS\lib\gcc\mingw32\4.6.1\include\c ++\tr1\stdlib.h>
//#include "time.h"
//#include "math.h"
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
DEFINE_PROFILE(inlet_x_velocity, thread, position)
{
// declaring variables
real x[ND_ND]; //this will hold the position vector
face_t f;
begin_f_loop(f, thread);
{
F_CENTROID(x, f, thread);
#if (dt) < 0.006)
F_PROFILE(for, thread, postion) = 1000 * dt;
#else if ( 0.006 < (dt) < 0.014)
F_PROFILE(for, thread, postion) = 0.5*dt;
#else if ( 0.01401 < (dt) < 0.028)
F_PROFILE(for, thread, postion) = 9.25;
#endif ( 0.02801 < (dt))
F_PROFILE(for, thread, postion) = 9.25 - (9.25 / 3)*(dt - 30);
return F_PROFILE;
}
end_f_loop(f, thread)
}

The above code is showing error related to udf.h , can u suggest possible changes needed in either code. As I am mechanical background I am not expert in coding in C++. The following were error shos- the udf.h is trouble:

Why are you editing and/or compiling the UDF source files directly in Visual Studio? I recommend editing files in a text editor with syntax highlighting (Notepad++ or SublimeText) and compiling/running the UDF in Fluent (see the FAQ section on compiling in Fluent).

[sanjeetlimbu]

I got it in fluent. thanks

[prt]

senjeetlimbu. i go thorough to your post and i am facing the same problem and same errors while i am doing programming please help what should i do, thanks in advance. please reply

[pakk]

You say you have the same problem as senjeetlimbu.
Did you notice that `e` gave an answer?
And did you see that senjeetlimbu said this solved his problem?
