Hello everyone,
I wanted to ask if there is anyone here who is familiar with calculating the U-values of disturbed and undisturbed walls. I need this to determine the Chi value. In principle, I understand the theory and can already calculate the U-value of an undisturbed wall, such as concrete.
Procedure for the undisturbed wall:
Define thermal data, set the indoor temperature to 20 Kelvin and the outdoor temperature to 10 Kelvin, perform the calculation, and evaluate the results—this part is clear.
The question is: how do I now model an insulation layer with a steel bracket attached to the concrete wall? The bracket’s contact with the wall is clear, but I am unsure about how the interaction of the steel bracket within the insulation should be represented. Should I create an empty component with the corresponding thickness and assign it a thermal conductivity? And how do I mesh an empty component?
Of course i could cut out the insulation with the shape of the steel bracket but thats quite complicated in 3D depending on the geometry of the bracket.
Very easy model to understand
Many thanks in adivce!
