how to i start reiteration
 
hi experts

In star-cd i am first give 1000 iter. but sol is not converged. then i am goto 2000 iter. but it start from again 1 to 2000. then how to start iteration from last value ( from 1000 iteration). please reply me. because if enter more no of iteration means sol not converged after 3 HRS also. less no of iteration means sol not converged then i am again start from 1 onwards thanks in advance

set solution restart from none to standard restart it will restart from thelast iteration ie when the last .pst file is written

hi thanks a lot ok. in tutorial 11 bouancy driven flow around a heatd fin in that tutorial i am vary the mesh size and base temp value. but tha values are not converged upto 30000 itera

in star_uguid they said use trasient analysis for conjugate heat transfer process. how we do this problem in traisient mode. how we define the time limits. thanks in advanse

u can change the first number in *.prob file which is default 1 to 2. 1 indicates start from scratch 2 indicate restart from existing .pst file. u need not star prostar again. just modify *.prob file. If u r running on parallel processor u need to copy *.prob in all the individual directories.
