'Cold bridge test 2' simulation project by clundstrom


I created a new simulation project called 'Cold bridge test 2':

Cold bridge test 2

More of my public projects can be found here.


Hi @clundstrom just stumbled over your project.

There was a simple problem in the temperature constraint which prevented a successful run.
Basically the problem is that there were nodes where the internal as well as the external temperature constraint was applied to, leading the system to an over-constrained state. I removed the duplicate external temperature condition on the beam and to enable a solution.

I an generally not really sure if I understood you setup correctly, as the temperature constraints not as I would assume them to be (basically I would only apply the internal temperature to the part of the beam which is in the room).

I made an additional change to also connect the beam to the walls, as in your example there was only a partial contact.
Here you can see the difference in the results:
