Steady-state simulation visualization

Hi all,

This is going to be a very stupid question. I apologize in advance. I am modelling a steady-state simulation of incompressible flow over an obstacle of 2000s using intervals of 200s. I am interested in studying the wake and the change in U magnitude. To visualize this, in the post-processing state, should I always select the last written interval? The snapshot at 2000s looks relatively different than the one at 600s for example. I guess this is related to the convergence of the results. Should you always select the last one?

Thanks in advance,
Daniel

Hello!

Since steady-state simulations are not time-dependent (i.e. you cannot draw any time-related insights from them), we are mostly interested in the converged state of the system.

So yes, a typical approach is to look only at the final results of the run. Note that it is a very good idea to evaluate convergence though.

PS: just to clarify, for steady-state simulations, we’re dealing with iterations. These are not correlated to time in seconds.
