Hi everybody
I'm trying to simulate plastic particles that move through wavy seewater. Now I'm firstly running a Simulation without an inlet velocity (just wave generation). I'm using the VOF model, k-Epsilon turbulence model and massless particles for a first simulation. The Problem I have now is that the massless particles seem to raise to the surface with the time (see picture particle track). It looks as if they have a lower density than the water. I don't understand that effect because if massless particles raise the convergence in the gravity direction can't be reached I think.

I tried different mesh sizes and the accurancy control is set at 10^(-5) and the track length scale at 0.005m (mesh size 0.15m, wave height 1.5m)

Does anybody have an idea what the problem could be?

Thanks a lot
