Hi,

I am a very beginner in FloTherm. I hope someone can help me with my problem:
I want to calculate how much the interior space heats up in one winter day using the solar modul.
I modelled a room, including a sun grabber (glass on the upper side) that catches the sun rays. Inside I have a layer of copper (red) that should heat up and transfer the heat to the interior space. In addition there is also a window above the sun grabber for additional heat. At the floor I put one constant heat source (23C).
It shows me the flow direction is like assumed, colder air is going down the grabber, hotter air is raising up.
So far so good. The problem is that the interior space heats up too much. Is it possible that copper heats up to more than 200C? and how can I simulate real conditions in the interior space? Because in reality in that room there would never be around 50C I assume.
In my case the solution never converges. What am I doing wrong?
I also still did not fully understand how to work with the transient solution.

I would really appreciate if someone could help me,

Ivan
