OpenFOAM Tutorial 3D floatingObject strange jump ?
 
Dear all!
I run tutorial floatingObject. I changed the mass:
It was:
mass=9.6;
I made:
mass=8.6;

The object is “jumping”. The run is blowing.
The reason of blowing is obvious: If the mass diminishes 10% object can’t jump.
Is it possible to run floatingObject with mass 10 % smaller and to receive normal results ?.

Thank you very much in advance,
Alexander.
