Hello everyone.

I am basically doing a simulation for air flow in a room.

What i would like to know if it would it be possible to specify a fixed heat transfer coefficient for the heat transfer into the fluid domain and a fixed surface temperature for a surface as boundary conditions?

Would it be possible with a UDF? I was looking through the UDF manual and saw that Define_Profile allow for the specification of a heat transfer coefficient, however i think its for an external flow outside the domain. Am i right?

CFX has this feature that allows for the specification of heat transfer coefficients via CCL by replacing the turbulent wall function.

Therefore how would it be possible to create a UDF to allow the input of both Heat transfer coefficient and fixed surface temperature into the fluid domain. If so can anyone direct me to a right direction.

Thanks alot!
