UDF help for Rapid compression machine ECM.
 

Dear all,


I am trying to create a user defined function udf for use in fluent ansys. Physics involved- i wanna get UDF- user defined function to get the following velocity profile for the body in ANSYS fluent- same velocities as piston motion stuff- for combustion test in fluent ANSYS software. The 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:\Program Files\ANSYS Inc\v150\fluent\fluent15.0.7\tgrid\win64\3d_host\l ocalize.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:

the localize.h is in C:\Program Files\ANSYS Inc\v150\fluent\fluent15.0.7\tgrid\win64\3d_host\l ocalize.h

Pl help . :)
