Hello everyone
I am trying to write 6-DOF UDF for dynamic mesh modeling. I have to control Center of Gravity motion in special condition. I used two DEFINE functions; DEFINE_SDOF_PROPERTIES and DEFINE_CG_MOTION. unfortunately it is not possible to use both at the same time. In my case, I have to control Center of gravity velocity while the body has 6DOF condition. I found a Macro ( DT_VEL_CG(dt)) which give the CG velocity, but I d not know how I can change the value.

thanks for your help in advance
