Hello,

I have a model of a tunnel. When running in transient, heat loss is being modeled through the walls. When switching the run to steady-state (the only difference), suddenly no heat is being lost through the walls. Is this a quick fix? Am I missing something simple or is more information needed on the model?

Thanks

If the transient model worked, but steady didn't check the temperature field. Steady is the equilibrium result so if there's no heat being added via a boundary/cell condition you won't see any heat transfer.
