Hello,

I want to simulate the heat transfer through a window placed between indoor and outdoor environmental conditions. After several failures, I reduce my model to just a rectangular that represents the window glass.

I define constant temperature walls for the two glass surfaces, and the top and bottom walls are adiabatic. But the heat transfer through the two surfaces are still not in balance, e.g., -116 W for the hot surface and 150 W for the cold surface.

I searched through the forum. Actually people had posted similar questions before, but no one had ever replied. Please help!
