Right, I.C. is for whole domain but it's not a guess it's initial system condition e.g. at t=0. for unsteady problems I.C. should be given to you like boundary conditions. you can't find I.C. just...

Ok, notice that I.C. in unsteady cases is a part of your problem it's not a first guess! you don't have permission to set it by chance. as you said, you want to trace second phase from t=0 to desired...

Hamid, if you want to see final phase positions, it's steady problem. but if you want to trace phase changing from specific initial phase positions then u should use unsteady solver and using steady...

Hi, your pictures recieved. as I understood, non of your parameters vary with time e.g. p=p(t) or ,... are they? in these cases you just have a steady problem that converge to result from an...

Hamid, if you solve steady case and then shift to unsteady solver, the results of converged steady solution will be your I.C. for unsteady ones! if you set another I.C. here by initializing or...

Hi hamid, if you use enough iterations per time step in order to reach convergence criteria in both cases, your result will not be different. this is a valuable tip for steady cases in which...
