Heat transfer modelling

I am now running a vehicle thermal simulation, and use the singel stream model to simulate the heat transfer, during calculating, there always arise the notice-Heat transfer temperature limited in the output window, who knows how to solve this problem, thank you!

If you are getting temperature limitations it's likely your simulation is diverging. Check your mesh and boundary conditions. Often it's prudent to run heat exchanger models for a few hundred iterations without heat to let the flow converge first.

From the residuals, it seems that the calculation didn't diverge, Maybe the mesh quality is the main problem, and I will take your advice to run another simulation to see the results, thanks for your reply!
