WUFI

Thank you, Thomas - that's such a clear explanation!
Best wishes,

Dear Forum, Occasionally when simulating structures that contain insulation, I notice a substantial gap between the brick and insulation layers, as shown in the image below. Could someone kindly explain why that gap is there or what it means? Screenshot 2023-01-05 at 12.42.15.png These gaps are also...

Hello! I applied the standard process by which we modify a layer to simulate a water-repellent treatment (A-value, etc.) and noticed that the moisture storage function of the "solid brick masonry" material (Fraunhofer-IBP database) remains unaffected. Does this make sense, when the surface...

Hello :) I'm looking at the RH - T isopleths produced by Quick Graph and wondered whether I could export to ASCII the LIM BI and LIM BII curves, or whether there's any other way of calculating the data myself. Also, what is the difference between BI and BII? (Perhaps something to do with the type of...

Thank you, Thomas! That solved the issue.

Hello. I attempted to edit the material properties of "Solid Brick, extruded" (TUV - not IBP) from the WUFI database and wanted to ask whether there is a reason that the software does not let me change the vapour diffusion resistance factor? Everything else seems editable. Many thanks in a...

Thanks for those pointers, Thomas. I've read through topic 3 in the documentation for the Thermal Transmission post-processor but would still like to clarify the following: 1) Are the moisture-dependent steady-state R-values (straight lines for dry, u80 and typical built-in moisture levels) in the p...

Thanks, Thomas, your explanation makes sense, although I can't imagine why WUFI would artificially U-values to zero if negative and not keep the absolute value, which would carry physical meaning. How can I find out more about how transient R-values are calculated, here? Many thanks, again, Apostolos

Hello. I am simulating the simplest of structures, a solid (Fraunhofer) brick with interior plaster, and I am looking at the transient U values as calculated by the thermal transmission module. For 2 months out of 12, specifically July and August, the U values are shown as equal to zero - see attach...
