WUFI

Big thank you for rapid resons

Just to be clear.
As I understand from the discussion WUFI always start calculation in year one on the correct date with wac files(looking ok in my resultfile).
This mean I have have several wacfiles för the period if i want to start calculation in year 2-8

Now I produced a 4 year file 19900101-19941231 (ran out of excelrows to be able to include eight years) .

When I am choosing my calculation period 20090401-20120331 (as I had in calculation previous ) there is no indication in WUFI that this should be a problem. I was expecting year 1-4 based on ...

Thank you. I found it in another mail reply later on.

Now i have created a couple of WAC files and then some other questions came up.

How can i get the correct year presented in the wac data or is this alwyas a synthetic year? This is also relevant when my measured data have different starting ...

Where can I find the tools folder and CreateClimateFile.xls

Trying to create a wac file but its hard without the excel sheet

The only thing I´m faking is the moisture capacity in the mineral woll similar to how airgaps is manipulated. But I will discuss a new purchase of 2D versions with my staff manager.

I´m using sources and sinks to simulate different rates of airchange in a ventilated airgap inside an exterial wall. 5,10,25,50 and 100 changes per hour is used. When i calculate I see that the temperature profiles inside the airgap is identical regardless of ventilation rate. I expected the ...

As I understand the only way to simulate mixed materials in a 1D program (brick walls, wooden framework with insulation) is to invent a new material with mixed properties.

When i calculate wooden framwork with insulation I have chosen mineral wool and added moisture capacity equivalent to 5% wood ...

I´m recently started to use Wufi to simulate external walls and a number of interesting issues with material data have revealed itself.

1. Material data is mostley measured in normal temperature conditions like 20 degrees celsius. In field measurements outer materials often reach tempertures above ...
