Particles at the bottom

Dear all,
I am wondering what happens to particles reaching the bottom (buoyancy module activated) ? Will they stand still (excluded for the rest of simulation) or continue to drift with bottom currents ?
Cheers

Hi Achref.

In principle, the particle will be excluded from the rest of the simulation (mortality OUT_OF_DOMAIN).
