Thermal Analysis Discrepancy

Hello,

A premptive thank you for anyone with information on this anomaly I have noticed in SW Simulation. I have an assembly with a sensor defined in SW determining the average temperature of a flat plate exchanger exposed to natural convection + radiation heat transfer. I have noticed that if I run the same analysis but change the orientation of the assembly (top view vs bottom view) the values I get for the average temperature change! If I repeat the analysis in the same orientation I get the same results, but as soon as I change the view and recalculate, the results change.

Any input is much appreciated!
