Hello all,

I am having a problem calculating the heat transfer coefficient and boundary heat flux as a result.

After setting up an expression report that was set to ${HeatTransferCoefficient}, I got the error "Cannot evaluate field function Heat Transfer Coefficient." Also something really weird is happening. I am able to get a value for a "surface average report of boundary heat flux on volume mesh" but I am not able to get the "surface integral of boundary heat flux on volume mesh."

Furthermore, when trying to output the heat transfer coefficient, I get a "no dat, undefined ratio." What ratio is not defined?

I am confused and need help from one of you experts.

Thank you all!
