Hi, I am trying to do an unsteady simulation over a 3D circular cylinder. I am interested in saving Iso-vorticity plots in velocity. As a general practice, I need to store my data after very small time interval over may be after every 60 time steps out of a total 60,000 time steps with a step size of 1e-6. If i save my data file with Autosave...each file has 280 Mb size so not feasible... How should i explicitly save the iso-vorticity files. I need to save them with non-graphical mode Fluent. Thanks, Endee

burn the results on CD's

Hi Ahmad... Cant we write some udf which can explicitly write the vorticity by its definition to a specific file. We may activate it through "execute command" after certain iterations. I dont think that the only feasible way is the one described by you? As we can find many people doing LES simulations etc and do you think they would have burned may be 400 CD's for one simulation? Does not seem logical to me. So is there some one who can guide or give some udf for writing vorticity magnitude only in 3D after certain intervals of time? Cheers Endee
