Please help me out with this problem... i am trying to load a UDF for giving a transient velocity and when i load it in compiled format this error comes.. what should i do.. should i use iterpreted/compiled???

Thanks in advance...

hai,
Check whether the environment variables are set properly for the VC++ installation. moreover ensure that the udf and case files are in the same location.

thank u byronsmith.. i will try it out...
#include "udf.h"
DEFINE_PROFILE(unsteady_velocity, thread, position)
{
face_t f;
real t = CURRENT_TIME;
begin_f_loop(f, thread)
{
F_PROFILE(f, thread, position) = 20. + 5.0*sin(10.*t);
}
end_f_loop(f, thread)
}

this is the program given in the tutorials... i saved it as .c format using notepad and opened it using fluent thats when i got the error.. if this works out i have alter this program for other cases... can u give me any instructions bcos i am new to udf's....:)
