Hi,

I am doing a transient thermal analysis and I want to continue the analysis until the steady state is reached (wich I don't know the time to reach it).

How do I select a steady state criteria to stop automatically the transient analysis (base on a temperature variation or flux for instance)?

Thank you very much for your help.

I suggest you use a Steady-State Thermal analysis to get the steady state solution.

Thank you for your response.
I need to use the transient thermal because I have multiple events during the analysis witch cause transient effect. After the final event, I need to continue the analisys till the steady state is reached.

Yes, but the boundary conditions after the final event determine the steady-state solution, so you can solve that quickly using Steady-State Thermal. Doing so will give you a final value for the temperatures you consider critical. I would have thought this would be useful information.
