Girish Saigaonkar Guest Posts: n/a	Hello Users, I am student of V.J.T.I.(Mumbai-India), and doing project in CFX.In my problem, I have to simulate a two phase flow in which gas is sparge at bottom then upto certain height there is liquid and gas and at that height gas escapes,then only gas escapes out of domain after some height.This is similar to Air-Lift Reactor. This condition can be given in CFX by 'step'function but it is available only for initialisation.Please kindly write to me How to make it for entire simulation. Regards, Girish.
