Hi,

Im trying to simulate the marine propeller using MRF approach. My solution is not getting converged and the values of epsilon is going like a waves as shown in the attachment. Can i treat it as a converged solution???

Thanks

Firstly can you tell us what are you trying to simulate?

Hi Amir,

I'm trying to simulate marine propeller using MRF approach.

Thanks

1-Calculate your case with double precision.
2-Define monitors for quantities of interest of your simulation and plot them as the solution iterates.

If solution is not converging and monitors show periodic behavior, Probably your simulation has some unsteady features (e.g., Vortex-shedding) and you should solve it in a transient manner.

Hi Amir,

I have already used double precision option.

And regd monitors I have plotted lift and drag but they are also having periodic nature. I'm trying to validate the base paper and he used steady state analysis.

Thank You
