Reply To: Question about radiation heat in ANSYS mechanical.

[Ilaria Salerno]

Thank you for your answer, Peter. My issue is that I'm unsure about the ambient temperature that I should set when simulating the radiative heat transfer from the satellite's external surfaces to the space, which is a required input besides the emissivity coefficient. Many suggest to set it to 2.7K, which is the estimated temperature of deep space, but I found that the steady-state solution drops in a not-realistic way (considering that I have also other thermal inputs, such as the solar direct radiation). Do you have any advice?
