Re: Fassade mit Ziegelbehang - Regenaufnahme

Hallo Sebastian,
den Regen würde ich hier auf 0 setzen.
Wegen der Belüftung würde ich eine Variante ohne Hinterlüftung mit dem geneigten Dachmodell, wahrscheinlich gering belüftet vergleichen. Ich schätze der Einfluss der Hinterlüftung ist hier gering.

Re: Air Layer Usage

Hi Dan,

the air layers without additional moisture show a bad convergence behavior in case of dew water. To avoid that, you can split them up, see here:

I recommend to always use the adaptive time step control in combination with ...

Re: WUFI-Simulation: Austrocknung Kupferblechdach (oxidiert vs. blank, Verschattung durch Terrasse)

Hallo,

generell ist es heutzutage nicht mehr zu empfehlen, außen dampfdichte Dächer ohne zusätzlicher Dämmung über der Schalung auszuführen. Dies gilt als Sonderkonstruktion und hat sehr klare Anwendungsgrenzen. Siehe hierzu auch Informationsdienst Holz - Flachdächer in Holzbauweise:

Re: wood fibre class in wufi Bio?

Hi,

In WUFI Bio Class I are the biodegradable substrates like paper, wood, other organic materials
and Class II are the non biodegradable materials like mineral materials, membranes.

So wood is class II.

Re: Automatic way of creating .bcli Files

Hi Oliver,

the bcli-Files are binary, as we are not allowed to give out the data for the climates for many external climate files. Therefore you can not view or manipulate them outside of WUFI. The only option is to generate these files in advance.

Re: Steady state calculation

HI Agnes,

sounds for me, like a normal climate files is used instead of your created one.
Try the following: copy your project folder, then delete input.dat as well as the *.bcli-files.
After that open the project in WUFI 2D again, reassign the boundary conditions and go to calculate. Now it ...

Re: Rammed Earth Wall

Dear Pauly,
some properties of the material should be known to choose the right product from the database.
Similar materials are probably something like clay our soil materials.

Re: Efficient way to extract moisture data from multiple elements in WUFI 2D

Dear Dennis,

the batch export is not possible here, but maybe some hints:
Have a look on the templates, there you can define a kind of auto-export.
You can export all series which are displayed in one diagram - further it is possible to drag and drop the series into another diagram. So my idea ...

Re: Wandheizung

Hallo Björn,

eine Wandheizung bzw. -kühlung kann in WUFI durch eine Wärmequelle simuliert werden. Allerdings ist es nur möglich, die Leistung in W/m² anzugeben, nicht die Temperatur selbst. Bei einem positiven Eintrag wird also Leistung addiert (Heizung) und bei einem negativen Eintrag wird ...

Re: Hygrothermal Reference Year

Dear Andris,

that depends on the data you have. For hygrothermal reference years normally measured data of about 10 years for all parameters are needed.
If these are included in the wac, you might be able to generate a hygrothermal reference year out of that. As far as I know, there is no automatic ...

Re: WUFI Graph Probleme beim Wiederöffnen

Hallo Sebastian,
danke für die Nachricht. Das ist ungewollt, das müssen wir korrigieren. Scheinbar wird beim wiederöffnen die Quelldatei nicht korrekt geladen.
Wir werden das so schnell wie möglich korrigieren.
