RANS2URANS

NIK

Hi,

1. If i want to convert a 2D RANS (steady) to URANS (unsteady), what changes do i require? ..particularly i am interested in setup of dual time stepping or pseudo time stepping concept...

2. Essentially, which factor is cattering for the unsteadiness now?

3. Linked with the previous..if i want to go for DES (Detached Eddy Simulation)..how to proceed with initial steady RANS code? Cheers NIK
