  Hi...I am trying to simulate the motion of a water(bottle) rocket caused by its thrust(ejecting water&air) using explicit 2 phase VOF ,Dynamic Mesh and 6 DOF UDF.Without 6 DOF(static simulation), everything runs smoothly but when 6 DOF is checked,pressure inside bottle becomes very high and both bottle and water appears static and finally AMG solver diverges.When I use air only everything also runs smoothly as expected(bottle shoots up)..What could the problem be !!!..any help would be appreciated.

  Hello,
  
  What are your boundary conditions? Can you send some picture for the way your problem is setup. It is difficult to judge without checking the setup.
