Floating + moving boundary interaction

edited March 28 in DualSPHysics v4.2

I'm running a case with moving boundaries and a floating body.
Initially the system looks like this

After some time dt the floating moves in the fluid domain

Once it reaches one of the moving boundaries, it sticks to that boundary and moves with it for some time

Eventually, I'm assuming it loses particles and to make up for it it gets bigger in volume since I'm using massbody.

I don't really know what's happening and why. How do floatings interact with boundaries?

Thank you!
