WUFI

I'm doing a simulation that is taking about 1.5 days to run with a file size of about 4.2 GB.
Three attempts in a row, at 53%, my machine is getting an error "Out of Memory".
Is this referring to RAM? WUFI suggests 4+ GB of RAM and I have 64GB.

Christian, I am also studying condensation within mineral wool. I'm following the WUFI Powerpoint at https://www.wufi-forum.com/viewtopic.php?f=8&t=1623 . I split off 1mm of mineral wool material, but it still has a water content that is basically 0 although I know RH and temp are very often hit...

When you say add a 1mm thick vapor barrier, you mean to draw a rectangle on the outside of the OSB? In other words, membranes should be modeled with thickness instead of a boundary condition between 2 materials? When I import a .dxf with <mm membranes drawn, they don't graphically show in WUFI 2D. I...

So RH% does not equal wmax?
And wmax requires a laboratory test to find; there's no reference information?

Now assume I somehow know wmax is 85%, if WUFI says a region of my material is 100% RH and under freezing temperature, that could cause damage because wmax has been exceeded?

That's really unfortunate because it's the main thing we want to analyze on our current project. In your link to the FAQ, it says "Frost-resistant materials usually can endure freezing water contents up to at least free saturation without suffering frost damage." What is "free saturat...

In this article https://www.buildingscience.com/sites/default/files/migrate/pdf/CP-1013_Assessing_Freeze_Thaw_Resistance_Clay_Brick_Insulation_Retrofit.pdf a metric called "critical saturation" is referred to. This is the amount of material saturation that will result in structural damage ...

I have an update. I tried a very simple analysis to troubleshoot WUFI Bio. I am just using the sine graph for climate. In WUFI Bio I can tell it's reading the full climate year. (First Image) When I look at the results, the curves only exist for the first month, which is why the traffic light is con...

I am opening a WUFI Bio file from an Isopleth Graph in WUFI Graph (Right click > Export to WUFI Bio). I can see the climate has been read from the results file which also generates a results graph, but the traffic light is greyed out. Under "Help" it says my time period is under 1 year if ...
