Default Heat Transfer Coefficient for Heat Flux = 0 W/m^2

Hello,

I applied for a high mach flow simulation over a plate the following boundary conditions for the plate:

Thermal: Heat Flux -- > Heat Flux 0 W/m^2 ; Wall Thickness = 0 m^2 ; Heat Generation Rate 0 W/m3

When I export the srf file for this surface, I get temperatures as well as heat transfer coefficients.

I am wondering, why I get heat transfer coefficients. According to the formula dot q = htc * A * (T_wall - T_Fluid)

So dot q is according to my settings 0 W/m^2.

So either the htc or T_Wall must be zero. But for both I get values. Why?

Does Fluent use for the wall temperature the stagnation temperature?

Thank you for your help!!

Best regards
CellZone
