I am simulating a case with a green roof using the Guideline for the calculation of extensive green roofs from WUFI.
In the green roof manual i see that you are supposed to add a moisture source in the substrate layer and set clipping to the source if it reaches free water saturation.
The problem is that i cant see any clipping criteria in moisture sources in WUFI 2D.
The calculation completes, but i see that i get quite a few convergence failures. I am guessing these convergence failures is due to the substrate layer getting oversaturated.
What i am wondering is if these convergence failures will have a big impact in the moisture content inside my roof. If the failures are only due to the substrate layer getting saturated, my thought is that this won't have that a big impact of what is actually happening inside the roof.
Thanks for feedback
