hello,
I am simulating a wave in tank with specified form of the wave. well, I have written the udf in notepad and then saved it as .c file:

#include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime) { vel[0]=(0.037098)*((1 - exp(-2.303*time))*7.7528*cos(7.7528*time) + ((2.303*exp(-2.303*time))*sin(7.7528*time))); }

but when I want to build libudf in user-defined function>compile it shows this error:
"system cannot find the file specified."

I have installed visual studio 2008 full but couldn't install MSDN library.
I have done what is said in one of the forums about setting paths variables in environment variables window in windows.
and also using winxp.

how can I solve this problem? is there any specific steps to compile a udf?

thank you my friends!
