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

If you are using a cluster (in this case paraFoam will not be useful), Put some probes on the domain (for example pressure probes) and investigate its history at each or some specified time.
