convergence problem in the turbomachinery problem.
what are the issue for the convergence of a simulation. In my case I am solving a centrifugal fan problem. In which I am simulating the impeller as well as the volute. I imposed the boundary conditions at
1) inlet : total pressure (0 pa relative pressure) 2) Outlet : mass flow rate: 3) impeller : Rotating wall; 4) casing :stationary wall; I am using the k omega turbulence model for solving the turbulent quantities. I set the convergence criteria as 10e4 for the velocities and the turbulence quantities. I am solving the momentum equations with High resolution scheme. I got struck when the simulation is not conversing up to the 10e4. but I want it must touch the criteria of the 10e5. Can anyone help me where may be the problem? Please suggest me. Thank you.
