WUFI

Dear Sir/Madam I load an external file of heating/cooling/dehumidification capacity to the calculation case. But It does not work. When I begin the calculation, the software shutdown. When I open it again, it does the calculation but the calculation result is unreasonable. When I output the dehumidi...

Dear Thomas
Thank you so much, it helped me a lot. But I have another question: Is it means when I am calculating the moisture flux between two grid elements, the liquid transport coefficient is dependent on the average water content of the two grid elements?

Hi, thank you for your attention. I was using WUFI Pro to calculate moisture transfer in ALC. I input the measured water content of ALC (6 points) and for the heat and moisture conductivity, I use the default value in WUFI. I know that WUFI use interpolation method to give Dww and water content in t...

Thank you so much dear Bludau!!! that helps me a lot!

I was calculating hygrothmeral behavior of the ground, and it needs a long time to heat up. So I was wondering is it possible to output the temperature distribution results at the final stage, and then input it as an initial calculation in a new calculation?
Thank you so much!

Hello I have a question about wufi 3d-object. I want to use 3D-objects to simulate an ungergroud building hygrothermal. However, WUFI wifi film about 3d-objects is not avaible anymore. I search on the internet and read WUFI help but cannot find more information about how to built a 3D-objects. I am ...

Thank you so much for your kind help. Below is the screenshot about the climate error. I notice there is a 3D-objects but I can not understand the relationship between “3d-object” model and the main “building” model. They are 2 separated models. If I want to simulate underground room heat transport,...

Hello I was a user of WUFI PLUS. I applied for a student license and I have two questions about it. The first question is a installation question. I installed WUFI on Windows 7 and Windows 10, but when I choose a climate data in Europe, it shows climate error when I choose a climate in Japan, it sho...

Dear Thomas,
Thank you so much for your reply. It really help me a lot!

Dear Lu, with constant boundary conditions only the redistribution is used for calculation. Speed will depend on the transfer coefficients of the boundary, diffusion/transport coefficient of you material, and also on the water content. Without more information I can not tell, if you did it properly...

Dear Lu, WUFI uses two liquid transfer coefficients (suction & redistribution) and as you wrote it is switched using the rain in the boundary condition. To use a different one you would have to change the coefficients in the material data. In WUFI light it is not possible to edit material data ...

Hello~ Thank you for your attemtion. I wrote a Fortran programme use WUFI equation to solve an 1D question (with initial condition are temperature 10C and rh 0.6 and constant indoor and outdoor temperature 10 C and relative humidity 0.6, 0.8 ). I use different liquid transfer coefficient(suction &am...
