May 19, 2011, 06:48	about Courant number	#1
kaifu Member Kai Join Date: May 2010 Location: Shanghai Posts: 61 Blog Entries: 1 Rep Power: 16	Hi Foamers, How to control/reduce courant number during simulation? I am doing simulation about two fluid bubbly flow (started solver from bubbleFoam). In my case I observed that the velocity of dispersed gas phase keeps growing at some point. Do i have to put a relaxation factor to the gas velocity? Would it help? (actually i've already put relaxationFactors=0.7 for the gas velocity) Thx. // Kai
