WUFI

In fact, the dipping test was made with a rendering (IRB H985 Z5). After 4 hours dipping, the measured water uptake was 0.38kg/m2. A coefficient of 0.19kg/m2h0.5 was deduced or 0.0031kg/m2s0.5. For the Wufi computation, most of the other parameters were measured. The following values were used: dens...

MeteoFrance peut fournir des données réelles mesurées mais actuellement à des prix exorbitants pour une série complète (>10000€). Méténorm est beaucoup moins cher mais c'est le résultat d'un modèle, c'est à dire que certaines données sont très précises (température, ensoleillement) alors que d'autre...

I have made a dipping test with a plain brick. The water uptake was measured and I have deduced the water absorption coefficient (kg/m2h0.5). Now I simulate this experiment with Wufi. It computes two values of the capillary diffusivity (at 100 and 80% RH). From these values, it computes the absorpti...

Wufi uses two liquid transport coefficient for suction and redistribution. I understand the following: When it rains, the coefficient for suction is used. As soon as it stops raining, the other one is used whatever the water content. When the drying of a fully saturated material is computed, the coe...

I prepared a new geometry in Wufi2d (Geometry) with the available drawing tool. A) In the next step, I went to the window "Grid". I got a red line " layer #8 has thickness zero". What does it mean and can I go on? B) I went to the window Surface/Climate. The geometry is shown the...

Hello To see the results, I use Wufigraph, open from Wufi2d. However I cannot close the software afterwards. When I want to close the Wufigraph, I get the window "wufigraph.xml (Access is denied)". I have to switch off the PC to get rid of the wufigraph page. By the same token, I get the f...

Hello
I am measuring the vaporisation of a water pool in a given climate.
Is there a way to use Wufi to simulate it?
In this case, how to describe the properties of water in the software?
Thank you and best regards

Hello I use Wufi2d3.3. I changed recently my PC and kept in parallel my old hard disc where my first version of Wufi2d3.3 was located and I can still open my Wufi files on this old hard disc. I reloaded Wufi2d3.3 on my new PC and it works well. Unfortunately I am not able to load my previous files i...

In Wufi5, it is possible to change the thermal conductivities of building materials. But I have not found how the properties of water and water vapor change with temperature in the software. Assuming that accurate values are available in the software, what is the max. temperature which can be realis...
