Dear TRNSYS users
I want to make simulations on highly insulated buildings.
Some of the walls I created bring a bug.
« Error creating the wall transfer function coefficients :
Stability criteria not fullfilled
Check layer definition (thickness, ratio of conductivity/density)
Please check the INF-file for further information »
I heard this could be solved by changing the density and capacity of the layer that causes the problem (here, a ceiling wood structure insulated with 40cm of wood fiber pannels (Steico))
But I cannot do this because I want to evaluate the impact of the inertia on the inside temperatures.
I tried by deviding the material in 2 layers: one would have the same inertia and the other, massless, would bring the thermical resistance. It doesn't work, stability criteria is still not fullfilled...
Can someone help me?
Thanks a lot
