WUFI

It worked !
Thank you very much Christian

I have the same problem.
I tried to copy and paste the IBP_24.mdb file from my old computer to my new computer. However Wufi had been updated on my new computer (version 5.2) whereas he is still in the older version on my old computer.
When I copy and paste the database file I cannot start Wufi and ...

Good morning,

I ran two simulations which are alike although I have included the screw fixing my insulation material in the second one, whereas in the first one I did not consider this screw. I wanted to see the impact of the thermal bridge created by the screw.
I was very surprised to see that the ...

Hello,

I have the exact same problem. Can you help me ?
Thank you,

Thanks Christian for your answer.

I think the errors came from a problem with the geometry of my room. Maybe some materials overlapped. Because when I remade the geometry I was able to have results.

I know that to solve this question Wufi Plus would be far more suitable, but I only wanted to have ...

The processing of my simulation is very quick (the end comes instantly even with 8760 steps).
Moreover, when openning Wufi Graph I have the following message "Selected positions are invalid for selected Wufi File"
And when I open Wufi Graph, I have the following message : "Read beyond end of file ...

That's it, I knew it was a stupid mistake !
Being too fast, I did like in Wufi 1D and I put the thermal resistance in spite of the thermal transmission.
It works well now thanks a lot.

Hi,

I am new on Wufi 2D and for every configurations I tested I have some results which are completely impossibles : my temperature in the wall is over 60°C (sometimes 100°C !) although it is 10°C on the oustside and 20°C on the inside...
I tried to simulate the same simple wall both on Wufi 1D and ...

Bonjour,

J'ai suivi une formation d'initiation aux flux hygrothermiques dans les parois du bâtiment ainsi qu'à l'utilisation de Wufi Pro (et un peu Wufi 2D) l'année dernière au CSTB Grenoble.
Je cherche maintenant à effectuer une formation plus poussée sur l'utilisation de Wufi et Wufi 2D, et sur l ...

Merci pour cette réponse.
Cordialement,

Bonjour,

J'aimerai savoir comment sont calculées les valeurs R (ou U) données par le module "thermal transmisison".

Quelque soit la paroi que je réalise, je fais face aux phénomènes suivants :
- les mois de octobre à avril se situent autour du R sec avec quelques fluctuations ce qui me paraît ...

Thank you very much for your answer

Good evening,

I want to export the graph that displays the profile of the water content in my wall at a chosen day.
When I go to the graph editor I can only setup profiles for the first and the last day of my simulation.
How can I obtain the graph for another day ? Is it possible ?
Thank you,

Thank you Thomas for your answer.

So how do you get the moisture storage function of an insulation material ?

Especially for RH above 90%, it is difficult to obtain the curve. Although I understood it is that part of the stotage function that will impact the results of a simulation. So it is in ...

I would also like to have some information about the pressure plate measurement for the determination of the sorption curve.
I want to have the sorption curve of some insulation materials.
Do you realise thoses measures at the IBP? At which RH do you do your measures ? How much does it cost ?
Thank ...
