calculating surface convective heat transfer coefficient

Whether it has the function of calculating the surface convective heat transfer coefficient

Hello,

It depends on the selected kind.
For kind 'Exchange coefficient', the exchange coefficient is constant.
For the kind 'Boundary layer' we use the following function:

h = h0 + c * v ^ e

v is the air velocity. h0, c and e are coefficients. Here is a picture of the corresponding boundary condition.

Ok, you can find an explanation of all output quantities in the output tutorial:
