Slowing down unstable multiphaseEulerFoam simulation -- CFD Online Discussion Forums

rahulksoni Member Rahul Kumar Soni Join Date: Oct 2013 Location: Bhubaneswar, India Posts: 68 Rep Power: 13	Why my multiphaseEulerFoam simulation is getting unstable after a small time of around 0.02-0.03 seconds. There is a sudden increase in Courant number to eventually drastically reduce the timestep. That makes the simulation much slower. How can I get rid of it or how to identify the problem creating job/operation/calculation.
