WUFI

Dear Sir/Madam,

I would like to model an air cavity in the assembly near the outside environment, so with rather cold conditions in winter. Infiltration of this cavity might occur by air exchange with the inside environment. So, condensation might take place.

The help mentions about the moisture ...

I noticed that results for other than south orientation can be obtained by saving the project (with the other orientation),restarting WUFI and re-opening the project. However, again, when changing the orientation, no differences can be observed in the results. So, every time I want to simulate ...

Dear support,

The orientation of a vertical construction has no influence on the temperatures. It seems that a south orientation is the default, and setting the azimuth to e.g. 180 has no influence on the results (temperatures still go up over 60 C for a north orientation in the test case, see ...

LS,

'Manual' grid definition is not always available. It seems to depend on grid size in the first place. 'Manual' is available only when the overall grid size (in x or y) is fine enough.

If this is intentional, what is then the reason?

Regards,

Willem
