Hello,

As with my previous posts I still cannot compile my function in Fluent due to system problems. I was wondering if someone would be so kind as to copy my .c file, compile it in fluent and then send me the compiled file.

Here is the UDF;

#include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime) { vel[0]=0.001*sin(1099557.429*time); }

If you could help me it would be great! Thanks, Leigh

For fluent 6.2.16, only compiled and not tested:

Good luck, RoM

Hello,

Thank you for your time in compiling the function. I expected this function to create a vibrating surface, but when I preview zone motion, the boundary just accelerates of to the left then stays at a point indefinitly. Have you any idea why this is?

Many thanks, Leigh

I dont use moving grids so i cant give you any advice for this problem. Maybe someone else who reads this?
