WUFI

I still can't get it to work and I get the message "WUFI fails to respond."
Please help!

Christian,
Would you please send me that list also.

Incidently most bricks are 75% solid to meet the ASTM specs.

MY OS is Vista Home Premium. I have been using WUFI over the past few days with no problem but today the program won't start. When I click on the WUFI Icon all that happens is a circle runs in the front of the WUFI logo screen. How do I cure this?
Thanks,

Thomas,
Is WUFI 2D fully operational? Last I heard that it was not user friendly. Is there a cost difference between the two versions? Can Pro 4.2 be upgraded? Can 2D be used the same as Pro 4.1?
Thanks for your reply.

I've read some of the help information about capillary action but I'm still confused. In interested in developing a sample of how the presence of external ground water may, through capillary action, be absorb into the masonry facade. How is this done and what is the relability of the results? Also, ...

Thomas,
Thanks for your suggestions.

Thomas, I received this response from the paint manufacturer: " A 2 coat system 10 mils dft (total dft) perm rating is 24.00 +/- 1.53 perms. " The structure is built on or next to a very wet area. From your response could water be drawn into the 1 1/2"ventilated air gap and settle int...

I read the previous topics on paint coatings and I have a parallel question. First, can a paint coating on the interior 8" wythe (4" CMU, 1" air, 2" insulation, & 8" CMU assembly) greatly effect the water or vapor transport capabilities of the wall section? Second, I am ...

Ouch, I should have looked at the ubits more carefully.
As a follow up, once the initial construction moisture is removed and the wall section goes through its normal yearly cycle of wetting and drying can an equilibrium point be determined?

I have run an analysis on a wall section and the Total Water Content Graph' value (lb/ft^2) is less than the sum of the water content of the individual members. How do I reconcile this difference?

Thomas,
Maybe we've reached the end of this line.
Thanks,

Thomas, The graph was for an average for the wall as constructed. The temperature and RH are averages for the month. With the above in mind what is the best analysis to determine if a wall (or specific point) has wetting or drying periods? Also, the graph is derived from hand calculations where WUFI...

Thomas,
I sent to support calculations and a derived graph. I tried to attach the graph to the forum page but it wouldn't attach. Would you please look at the support page for my question?
Thanks,
C. Furtaw

Thomas,
The conversion is no problem, I just wanted to make sure what were the units before I went to far.
Thanks,
C. Furtaw

Thomas, With he information that you provided and using the data I supplied above below is what I derive from this data in the 2nd and next to last rows that I think was for the 11th month: 2nd row: x coord. .00297 in. temp. = 9.5 F 82% RH & 2.4 water content (I have to cehck the units) next to ...
