 May 15, 2012, 12:28 Run Calculation #1 New Member   kris pani Join Date: Mar 2012 Location: Greece Posts: 14 Rep Power: 14 Hello genius!! First of all sorry for my mistakes... English is not my native language !!! So, I have to simulate a can pasteurization and watch the thermal increase at the slow heat zone (shz)...My question is : what should I do in order to take the correct results (about the time of shz simulation) at Run Calculation option ? How i choose the time step size (s) and the number of time steps ? I have read many tutorials but still I have doubts...My problem is transient 3-D, double precision, pressure – based, laminar flow, natural convection... Theoretically I need 2400s for the slow heat zone to get my desirable temperature. Thanks a lot !!!
