Re: Heat transfer coefficient

For calculation of convection coefficient --I usually use the dimensionless numbers and calculated base some empirical correlations .
here I have to make this calculation and then put the number in sif ?
Do you have any example about calculation of this factor for Elmer ?

Heat transfer coefficient

Hello,
I am trying to use the elmer fem for thermal analysis of electrical machine . I have some problems in the boundary definition the Heat transfer coefficient means the natural our force convection coefficient plus radiation?if it is not correct how can I calculate this element ?
