Monitor Position

Post by C. Furtaw »

I used the monitor position to see what happens to material at different position.
What exactly am I to learn from the data graphs for Temperature/Dewpoint and Isopleths? How does this relate to the water content of the material?
Thanks,

The Relative Humdity is related to the water content of the material by the moisture storage function (in the material properties).

Normally the monitor positions are used to see weather you get condensation water or mould problems at the surface or the interfaces of two materials...

If needed you can also extract the water content for a certain position from the WUFI film by right mouse click in the film - create course and then left mouse click in the desired grid element (the thin dark blue courve is the water content in this grid element - the thicker curve is the water content in the whole material layer).

Daniel,
Can you give me and example with numbers, for OSB, of the relative humity, water content, and moisture storage function?
Thanks,
Carl

If you use the Oriented Strand Board from the generic US data base and look in the moisture storage function (you get the numbers if you change from graph to table) you find for example for a RH of 0,895 a water content of 104,65 kg.

That means that at 90 % RH there is a water content of about 105 kg in the material....
