If they are not tight enough then you converge tighter. And you should do a sensitivity study to determine how tight you require.

This is very important for CHT simulations - residuals are not a reliable guide of convergence for many CHT simulations.

You often have to use a solid time scale factor in steady state simulations to accelerate convergence in solid regions. If you are not using this parameter convergence can take forever and it can...

You will get heat flow between the solid and fluid domains when you use the default Conservative Interface flux model on the interface. The Thermal contact resistance model will add thermal contact...

You should define whatever reference temperature makes sense in your simulation -probably the inlet temperature, the initial temperature or something like that. Inadequate mesh resolution is the...

I would have a look at your HTC (using a sensible reference temperature) to see if it is realistic. I would then do a sensitivity analysis to see if it is accurate. I suspect the results you have so...
