Hi,

I've to analyze a body that is traslating and rotating at the same time (2d case). My problem is that the omega i set is always refered to the absolute z axis, while i want it refered to the axis paralel to z but passing through the CG of the body. Here my udf


#include "udf.h"

DEFINE_CG_MOTION(spin,dt,vel,omega,time,dtime)
{

omega[2]=76.34;

}

What can i do?

thanks

Solved... I only needed to set inizial cg position in the dynamic mesh panel :P
