How to verify whether simulation has reached steady state?

vidyadhar · February 8, 2017, 02:40

Dear All,

I am beginner and using openFOAM.

I am using Transient solver. How to verify whether the simulation has reached steady state. Do we have to check the variations in properties at all spatial locations or do we have to take averaging.

Or, Is there any other way to do this?

Thanks & Regards,
Vidyadhar

Hello vidyadhar

are you averaging your fields in time? When the average keeps constant in time you can consider that you reached the steady state.
