We will not be able to give you any advice on your simulation set up or which options to try in that case. But general comments: "How can I verify the "periodic steady state" is confident enough...

Do not use tiny timesteps (unless your geometry is tiny and requires it). It will make the residuals decrease, but it is not real convergence. It is just the tiny increments from step to step are not...

The main reason is because if the flow has transient behaviour then a steady state simulation will never converge because it is not steady. These flow transients are very common in fluid flows - they...
