Hi

I am modelling a plate coming dwon onto the surface of liquid. When i am doing this using DEFINE_CG_MOTION, the plate passes through the liquid as well as the wall below the liquid. I dont what it to happen. Could anyone help me with it? Does the DEFINE_CG_MOTION macros takes into account solid body motion?

Thanks in advance... shanti

You need to define more accuratly your wall motion in order to avoid such case: it doesn't take into account interactions between 2 solids except if you precise this in your udf programs

Perhaps something like: if (cg_position - wallposition) < 1e-3 then v = 0
