Hi @ilkin,
It is difficult to say what realy is hapening. It depends a lot on the different material definitions and the time step of the simulation. General you can expect the following to happen.
-
Window: Part of the radiantion will pass through the window and will enter the room. That is why rooms with big windows facing the sun can heat up too much. The outside surface temperature of the window will therefor be less.
-
Wall: Heat radiaton from the sun will be partly abosorbed and partly refected by the wall. No radiation will pass the wall. Because of this absorbtion the wall heats up. So the temperature of the wall surface is probably higher then the temperature of the window surface.
-
Outside temperature: The mean radiant outside temperature is calculated with view factors. So if there is a surface with a high temperature nearby the place where you are standing, you will feel the heat of this surface. Just like a radiator.
In the following link you can see a simulation I made of surface temperatures during a hot summer day.
The loading of theanimations is quite slow. (have some patience)
