my udf problem!!!
Hello everybody
I want to compile my udf in fluent. the udf is is a simple parabolic velocity profile in pipe and inlet. as shown below:
Code:
/***********************************************************************
udfexample.c
UDF for specifying steady-state velocity profile boundary condition
************************************************************************/
#include "udf.h"
DEFINE_PROFILE(inlet_x_velocity, thread, position)
{
real x[ND_ND]; /* this will hold the position vector */
real y, h;
face_t f;
h = 0.186; /* inlet height in m */
begin_f_loop(f,thread)
{
F_CENTROID(x, f, thread);
y = 2.*(x[1]-0.5*h)/h; /* non-dimensional y coordinate */
F_PROFILE(f, thread, position) = 1*(1.0-y*y);
}
end_f_loop(f, thread)
}
at first I am using windows 7, ansys fluent 16.2, Microsoft visual studio 2008. also I have Microsoft windows SDK 7.1. when I want to compile my udf, I use two methods. first: running fluent with Microsoft visual studio command prompt and second:running fluent with Microsoft windows sdk 7.1. also my case, .c and .h files are in same folders. with first method, it seems very good in "build" item. but the problem is with loading that gives me error as shown below:
build:
Code:

user_nt.udf file is outdated. So, recreating the file for 2d ...
(chdir "libudf\win64\2d")(system "copy "C:\PROGRA~1\ANSYSI~1\v162\fluent"\fluent16.2.0\src\udf\makefile_nt.udf "libudf\win64\2d\makefile" ")
1 file(s) copied.

but when opening case file with microsoft windows sdk it gives:
