Hey all,
I am doing a heat transfer problem. I divided the problem into two simulations. The first one is an external flow over a heated body. From this simulation, I will get the heat transfer coefficients(HTC) and in the second simulation, I am planning to do a CHT simulation where I need to use the HTC that I got from the external flow simulation.
Currently, I am assigning the area-averaged HTC from the external flow simulation to the CHT simulation. What I need is a one-to-one mapping of the HTC to CHT simulation since both are done in the same geometry.

Thanks for the help.

write to profile HTC from simulation and apply it as boundary condition

agree with Alexander. However, i am confused on why you don't simulate the full problem in one run.

Thank you, Will try it.

The reason why i simulate the problem separately is because of the mesh number of elements. What i am try to simulate is a heat transfer analysis of electrical motor which is cooled by external forced convection. So if i am simulating both external and internal fluids(there is air inside the motor), then my mesh count will be very high which makes the problem computationally limiting for me.

Thanks for your reply.
