WUFI

How do I move my user defined material database to a new machine?

Are climate and material databases transferable from WUFI Pro 5.3 to WUFI Plus 3.0?

I see that there is a new version of Pro. Where can I access it?

Thanks

I am having trouble with the new version of Bio, my results are very different from the old version and a lot less conservative. Is there a place to download the old version?

I am also trying to install the climate add on with WUFI Pro 5.1.0.559 DB 24.71

Is there an update that I missed?

I've been using WUFI Pro 5.1 for 9 months now, suddenly today I cannot get it to load. The intro/license screen comes up but the program does not load. I uninstalled and reinstalled it, to no avail. I eventually have to force quit as it bogs down my entire computer.

I have checked the barometric pressures, there are no 0 values.

Could the error come from the 3 year length of my weather data? When my calculations run the current date runs up for almost 3 years and then jumps back a year before giving me the error message.

I am using moisture sources.

I'm using climate data for Fairbanks, Alaska, that I've put together using the create climate spreasheet. That seems to be my problem, using a location from the map works just fine. I have 3 years of local weather data that I've exported to a .wac file. Any ideas what ...

When I run my calculation I get a "floating point division by zero" error. I can run the calculation for 2 years, but when I try to expand it out beyond two years I get the error.

Here is the start of my .WAC file.

I have created a climate file using 3 years of data in the CreateClimate.xls spreadsheet. It exports to .WAC fine and loads into WUFI.

When I review the data in WUFI all but the RH is incorrect. In the Temperature/Relative Humidity dialog the temperature graph is incorrect, it is too flat with no ...

My calculations are stopping because of diverging results. I have walls with and without a vapor barriers and a moisture source. I've tried changing the clipping but that doesn't seem to help.

In the Status of Last Calculation dialog my clipped moisture sources always read 0. I am unsure what this ...

Ah, I see I needed to extend my source to the plywood sheathing. I am getting much better results now. Thank you.

I've set up my moisture source as a air infiltration model IBP for the whole layer.

air tightness class C

ventilation overpressure of 8

no clipping

I've tried a other tightness settings, but the results are always the same.

I am trying to model a wall with an interior vapor barrier that has a rather large hole in it. When I create a moisture source using the air infiltration model the results are identical to the model without the source. Is there another way to model an interior vapor barrier with a hole?

Thanks ...
