Default Total heat transf. rate vs Total surface heat flux

I'm trying to simulate heat transfer through a wall to compare with known correlations. When I compute the heat flux with the surface integrals (Report-surface integrals - total surface heat flux), it gives a value that is in accordance with the outside and inside wall temperatures, being that flux equal to the conduction heat flux.

However, using the Report-Fluxes - Total heat transfer rate - it gives a value higher than that. Does anyone know why? I'm not using any radiation model.

Thank you.

Hello there,

this is quite old, but did you get an answer to that?

Best,
David
