Hello,

Now I have installed the new OF170, when I try to run the floatingObject example from multiphase/interDyMFoam tutorial I obtain the following error:

Hello,
I still continues trying to run the floating tutorial case.

Anybody know what it is possible that alpha start to increase and produce simulation crash?
