Interior Temperature

hi,

I am a very beginner in FloTherm.
I am trying to calculate how much an interior room heats up using solar energy.
But even if I don't use solar, no radiation and an outside temperature of 10C, the interior temperature is 35C. I don't even have materials in my model yet.

Can someone explain me why? I would like to drop the temperature of the interior to 22C.

Thank you very much

do you "re-initialize and solve" after each modification?

Hi Gabriel,

Thank you so much, I totally missed that!! Now it works properly!

Maybe you know also how I can change the interior temperature to 22C?
Because now I have of course outside and inside the starting 2C, so the interior heats up very slowly. But I would like to start with real conditions!
Do I have to work with the wall properties like thermal, surface exchange to give a temperature or is there another solution?

Thank you in advance
