Hi everyone,

Anyway i'd like to install the non-commercial version of WUFI ORNL, but i'm afraid there will be again the problem i ...

Thank you for these advices, i'm about to understand the problem...
I've change the names of folders, and it's ok, i have now the right path : i don't have error messages when i open WUFI, and i can see the names of cities on the map.

But... when i choose a city, i can see the continent, the ...

Well, thank you very much, and it seems quite "simple", but it doesn't work, even if i've done everything correctly. If you have some additional advices...

Best regards

climate files don't appear on the map !

Hi,

I've downloaded yesterday the WUFI ORNL version on my computer, and now, when i use my "traditionnel" version (WUFI 2D), there's no more climate files on the map.

In fact, i've searched them on the correct repertory and they are the climate files, but "in blue", as if there was a problem, and ...

Bonjour,

Il faudrait vérifier, mais j'avais fait quelques essais labos lors de mon erasmus en république tchèque là dessus (avec des normes différentes donc), mais en gros le coefficient d'absorption A (en kg/m².s1/2) était le coefficient directeur de la droite obtenue quand on traçait la masse d ...

I'm not sure i've understood very well your problem, as i'm quite a new user of WUFI, but I think i had a similar problem, a saturation phenomena always associated with rain in the weather file. And this is the space to share problems, so maybe it can help ?

In my case, the Water content was ...

Merci beaucoup Amandine pour ces précisions sur les propriétés, j'ai pu ainsi sélectionner plusieurs pierres qui correspondent un peu mieux à mon étude, dont la pierre "Sandstone Posta", de la base de données MASEA.

Elle présente le même "problème" d'angularité pour la courbe de sorption, mais je ...

Choix des matériaux - propriétés

Bonjour, c'est encore moi :)

Je reviens vers vous car j'ai plusieurs questions à propos du choix de matériau pour la simulation et les conséquences qu'un choix peut engendrer (notamment au niveau des problèmes de convergence).

J'ai modélisé un exemple de paroi en béton, mais ce qui m'intéresse en ...

Bonjour,

merci de cette réponse rapide, le fichier était bien identique, mais je n'avais pas utilisé CreateClimatefile.xls, j'avais juste modifié "manuellement" en ouvrant avec le bloc-notes... le problème devait venir de là.
J'ai heureusement retrouvé une copie dans un dossier que je n'avais pas ...

Bonjour,

je dispose d'un fichier .wac, commandé chez meteonorm il y a quelques temps, et avec lequel j'ai pu faire quelques calculs, mais depuis quelques jours WUFI ne le reconnait plus, en m'informant qu'il ne reconnait plus le format du fichier.

Il reconnait cependant les autres fichiers .wac ...

Hello Christian,

if you cancel the Dw at the free saturation there will be no further transport.
Totally right, I just didn't know how to stabilize the element and it seemed to work since it gives time to the unsaturated elements to redistribute water, thus increasing the humidity gradient ...

Source in Wufi 2D

Hello,

I'd like to know what are the units given in wufi 2D in order to get a correct "source" file:

For heat: is it Sh = sh*dx*dy ? so [Sh] = W/m
For moisture: Sw = sw*dx*dy ? so [Sw] = Kg/(m.s)

Thank you.

Hello Christian.

Concerning you answer I have another question:

regarding the free saturation of the materials, shouldn't Dw be cancelled above free saturation? (since no more capillary action is possible)

Dw(w>wf) = 0

Ok, if Dw is cancelled then water might stay in the structure, but then ...

This helps a lot! I was thinking about local Dws/Dww depending on each element of the grid, but now it's easier to explain.

Thank you!
