Error compiling UDF.
 

Hi guys,
I want to create an udf to input a sinusoidal movement to a wall of a tank, so I have made a .c file with this code (found on web) for example:

#include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime)
{
vel[0]=(0.30823)*((1 - exp(-0.417*time))*1.0472*cos(1.0472*time) + ((0.417*exp(-0.417*time))*sin(1.0472*time)));
}

Now, I receive an error "nmake" (or something similar) when I try to load it and build a libudf. I'm using fluent 14 and to compile udf "Vs2012 Express for desktop" or "Dev-C++"...I've read by tutorials also something regarding folders and sdk commands' prompt, but I didn't understand :-(

can anyone help me to resolve this problem step to step, please?
Thanks in advance

Please provide the exact error message that you see when you try to compile.

Hi pakk,
thanks for the help but I've resolved the problem loading fluent with the prompt of commands :)
