Hi all,
Recently, I have been studying the unsteady simulation of pumps by using OpenFOAM. Then, I try to simulate the Timisoara swirl generator case with transientSimpleDyMFoam solver firstly. The solver and case are both downloaded from the webpage: http://openfoamwiki.net/index.php/Sig_Turbomachinery_/_Timisoara_Swirl_Generator But, the case was diverged after several steps, and the log file is in the attached files. I don't know why it was diverged though I haven't changed anything? Would someone like to help me? I will appreciate it! here is the setup of fvSolution and controdict: fvSolution file: Quote:
Controdict file: Best Regards, Yun Ren

You may want to switch off the relative tolerances in the pressure solver.

Hi Sandeep,
What do you mean about switch off the relative tolerances in the pressure solver. Sorry, I can't understand. Could I have some more details, please. And I just sent an email to you. Hoping for your reply. Thank you very much! Regard, Yun Ren |

Sorry for being cryptic. Set relTol to 0.0 for pressure in fvSolution.
