WUFI

We just released WUFI Pro 7.1.10.3 where this issue is fixed.

Best regards

Hi,
can you please send us the logfiles to "support at wufi dot com".
You can them in the folder: Just insert that into your file explorers address field.

Please send wufi7.log and vtt.log from a date, that happened.

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 ...

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 ...

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.

Hi,

yes, sorry for that, thats a bug, thanks for reporting and sorry for the inconvenience.
We will solve that as soon as possible.

By the way, did you check your balances? Your course looks like there are problems in the convergence. If the balances differ much, the results should not be ...

Hi Katrine,

with rain from the outside, the surface takes up water corresponding to the available pore volume and rain. This is redistributed into the construction depending on the liquid transport coefficients of the other layer. There is no seepage flow. A source is bringing in an additional ...

Hi Amal,

the thermal conductivity depending on the water content is handled in the "Thermal Conductivity, moisture dependent":

Hi,
problem here is, that the source strength, which is introduced by the infiltration source is much lower than the water content the masonry wall already has. Therefore you will not see a difference. You can see the source amount brought in in the table "Status of last calculation". This is also ...

Hi Mir Hedayat Moosavi,

You have to multiply with dx, as long as your source is not related to a boundary, then it would be the dy for vertical boundaries.

The conversion is as follows, here as an example 100g/m² distributed over three month:
Conversion g -> kg: 100[g]/ 1000[g/kg]= 0.1 [kg]
Time ...

Hi Andris,
please check, if the balances are ok. Looks like you have problems with the convergence. That might be caused by condensate forming in the outer insulation?
Christian

Hallo,
aufgrund des großen Porenvolumens würde ich schätzen, dass Porenbeton weitgehend frostsicher ist. Ich würde aber empfehlen, beim Hersteller anzufragen, der sollte das wissen.

Dear Lee,

the difference between DIN and FSP is the moisture storage and liquid transport.

Soil DIN (DIN = German Standard Institute) is derived from the standard which only contains basic values. It uses a internal moisture storage function based on the porosity and more important - it does not ...

Hallo,
das ist schon so möglich, aber auf diese Weise wird in der eindimensionalen Simulation der kapillare Transport durch die Stege vernachlässigt.
Hochlochziegel gibt es ältere in der Datenbank unter dem Namen:
Hochdämmender Ziegel
Für Bimshohlblocksteine liegen uns derzeit keine Daten vor ...

Hi,
this file wants to create the wac-file in the same folder as the xls-sheet.
Please try to first save the xls-file to some folder you have full access, like your documents and then try again.
