WUFI

Dear sirs,
I have just started modelling a building in WUFI®Plus using the 3-D Editor and came across the following doubt: When defining a wall, the vertices that we input should correspond to the coordinates of the wall’s outer surface, middle or inner surface?
Thanks in advance for your help.

Dear Mr. Hurd, I am student of university in Portugal, and I am currently doing a PhD about moisture storage characteristics of porous capillary active materials. When i read the document: " Determination of moisture storage characteristics of porous capillary active materials", i stayed i...

now , i understand.

thanks for your complet answer.

I said this, because i looked for the formula of Dws(W)= 3,8x(A/Wf)^2..., this formula is in the help of topic:" liquid transport coefficients" .In this formula, exist one relationship among Dws and Wf (free water saturation)???

Regards

Dear wufi team I saw a WUFI-help of liquid transport coefficients, and i read: there is little capillary conduction above free saturation, the liquid transport coefficients for this moisture region are very low. Then, How can you explain, that one smaller free water saturation cause more liquid tran...

thanks a lot for your good and complete answer.

Thanks for your answer. Only other question:

When RH=100%, the situation is of free saturation or maximum saturation??

REGARDS

Dear WUFI team,

I am studying frost damage risk, and i read a document in wufi forum about free saturation and maximum saturation.

I want to know:
what is the diference between free saturation and maximum saturation?
where I can find this properties in wufu?

Regards

Hi

I need to calculate heat transfer coefficients for surface exterior, but it depend the format of climate file (i saw in the help). For lisbon climate file, what is the format? TRY/ DAT /WET.....

Thanks for your attention

Hi

the Wufi may consider any chance of shading the facade exterior?

Hi

In the menu : " Initial Conditions", have a choice: assign Typical build-in Moisture, when i choose the option : " in each layer". What is mean it? What is typical build-in moisture? i try to find at help, but I did not found anything about it.

regards

I am Fernando I saw the document: " effect of interior and exterior insulation on the hygrothermal behaviour of exposed walls"(this document is on this site Wufi). In this document i read about impregantion , that should be applied to the facade, for improve the moisture situation provoked...

Hi , I am fernando I have question , that is: In help, i found the process of calculating the properties of materials (ex: bulk density), but where it is written, the standards from which it derives these calculations? I need this, to put on my dissertation, is required by my teacher. bye, thank you...
