WUFI

Hello! I've been modeling a outer wall's inside corner in a passive house. The house has wooden frame. Model enclosed. In the first model I made I removed the wooden facade paneling so I could ignore rain, which always seems to mess up the calculations. The inner thermal insulation (aluminum coated ...

Hello again! I'm having trouble again. I made a small modification to the roof structure by adding a vapour barrier on top of the hollow core slab. All the calculation options are as before, but for some reason, after a few time steps the iteration is halted "***TERMINATED - inner iterations di...

Thank you Christian, I followed your instructions and the problem was solved.

Hi!

I emailed the support and was advised to update Wufigraph. This solved the problem.

Thank you very much.

Hello! I've tried to simulate a flat roof structure (picture 1). The materials are (from bottom up) hollow core slab 265 mm, EPS-concrete pouring 120...220 mm, hard mineral wool 370 mm with ventilation cuts (15 mm x 25 mm), roofing felt (bitumen), gravel. Geometry and and grid are in picture 2. For ...

Hello! I have a simple problem. I can't open Wufi Graph. When I click the icon, the logo jumps on the screen as normal, but it quickly disappears and nothing happens afterwards. This happens no matter where I try to access the program: Wufi Pro, 2D or straight from the file directory. It's been a wh...

Hello! I'm modeling a massive masonry outside wall (600 mm, uncoated) and whenever I have driving rain on, the whole brick layer gets wet rather quickly. This is odd, since I've never encountered abnormally high moisture contents in massive masonry outside walls. Should I add a surface condition wit...

Hello! Is it possible to simulate a model with a ventilated air layer that isn't outdoor air or indoor air? In my model there is a cooler room element (-24 celcius) complete with insulated floors, walls and roof, basically a panel-sandwich-construction. The cooler room element is inside a room on th...

Hello! I need to simulate couple of floor types. One of the floor types has a hollow core slab at the bottom as supporting structure and on top of it, there is thermal insulation, in-situ cast concrete slab, screed and floor covering. It's a bit like a concrete sandwich panel as a floor. I have to m...

Hello, I've been simulating the behaviour of an in-situ concrete slab after it's been covered with a flooring material (vinyl, linoleum, etc.). According to the norms here, a concrete floor may be covered with flooring material (plastic flooring) when the RH is lower than 85 % at 20 % of the slab's ...

Hello! I was wondering if there's a good, established way of simulating the ground and constructions connected to it, particularly floor slabs. I'm currently trying to simulate a in-situ concrete slab and see how it behaves with different coating materials. My structure is as follows: 200 mm 8-16 mm...

The work-around I mentioned in earlier post seems to be working and it's not very hard to do, so I'll stick with it. Problem solved!

Mods may delete this topic if they see fit.

Ok, I checked this thoroughly again and found out that WUFI always read the initial conditions -file as absolute water content data, even though I had used the model's RH-profile exported in ASCII. Is there a way around this? I'd like to simply provide WUFI with a file with a RH curve instead of che...
