Hi Josephine,
if the modelling direction is not explicitly defined by the problem statement, a horizontal section is usually assumed in WUFI 2D. In that case, the model represents a cut through the wall in plane, for example to study horizontal moisture transport or local effects.
However, it is ...

Re: Wall Assembly with multiple metal layers - Initial RH question
Hi Nick,
from my perspective, it would be more appropriate to set up the model in such a way that it can also be evaluated reliably with an initial relative humidity of 80 %, rather than reducing the initial moisture level solely for numerical reasons.
The observed B1/B2 balance discrepancies at 80 ...

Hallo Edbs,
der Beton kann vermutlich die Feuchte schnell aufnehmen.
Im Film müsste man das sehen können.

Re: Courbe eau contenue atypique
HI Guillaume,
these peaks are related to problems in convergence. Do the balances match? I guess not.
Please try to split the air layer according to this topic:

Re: Wood fibre in pitched roof
Hi,
until now, the WTA curve has actually been intended for softwood. However, many wood fiber insulation materials are even more durable than wood, but not all of them. If in doubt, this should be clarified with the manufacturer—for some materials, this is already known, otherwise testing options ...

Re: WufiGraph lose link with wufi results
Hi Tom,
I can reproduce that on one of my computers, but not on an other. We have to fix that somehow.
There is a workaround to reconnect the file. Rename the w7p-file or change the path before loading WUFI Graph - then it will show you the file as missing and by clicking on it, you can select the ...

Re: Innendämmung mit/ohne Dampfbremse
Hallo Raphaela,
wenn die Konstruktion ohne Dampfbremse besser abschneidet, dann ist das wahrscheinlich tatsächlich über die bessere Trocknung zu erklären. Wenn die Konstruktion direkt trocknen kann, sieht man die anfängliche Umverteilung ggf. nicht.
Das ist so schwierig zu beurteilen. Speicher doch ...

is this related to results from WUFI Pro 6 or 7?
Which version of WUFI Graph do you use?

Re: High Convergence & Balance Error in Wall Assembly with imervious layer
Dear Nick,
which version of WUFI is this related to?
Such convergence problems are often related to high water contents in the air layer. Did you use the air layer without additional moisture storage?
