Re: Ventilated Cavity about 1500mm² air gap with open joints - Delphin 6 settings

Hello, It looks fine. The only thing is point d) Here you calc an additional resitance. Why? Of course you can use the contact condition with the air-material interface variant. But this is not an additional resitance. It replaces the normal averaging. Furthermore you take the radiative part into ac...

Re: Influence of surface type in VTT mould model

Hello,

I got once a Excel file with an updated VTT model from Tampere University. You can download it here:
https://datashare.tu-dresden.de/s/BtxPrHaB2mnWp32
There you find this calculation and from this I derived our model. Unfortunately I don't have further information.

Re: Export animation as image stack or video

Hello,

Since version 2.5.4 exist a feature to create and store animations. You will find it as a red button in the time slider widget on the right bottom area of the main window of PostProc 2.

Re: Ausgabedatei als %M statt kg/kg

Hallo,

Das würde schon gehen, aber erst in der nächsten Version. Die ist allerdings fast fertig und in ca. 2 Wochen auslieferbereit. Du kannst diese Multiplikation aber auch direkt im PostProc 2 machen. Da gibt es einen Manipulator den du verwenden kannst.

Viele Grüße
Heiko

Re: Non-rectangular area selections for output

Hello,

You can only select rectangles. If you have such a non-rectangular shape you need to assign all including rectangles separately. You can assign more than one rectangle to the same output. Only keep the output selected and assign one rectangle after the other.

Re: Air movement at corners

Hello,

You need to provide a separate boundary condition (surface) there.

Re: Built in moisture

Hello,

You can set initial conditions in DELPHIN to each point of the construction. I will send you a detailed explanation by e-mail. Its a bit too long for the forum.
You can set moisture content in different units like m3/m3, kg/m3, %RH or kg/kg

Re: STEAM

This sounds like a own boundary condition for the inner side.
You can switch the type of the interface for inside to the detailed model. Here you can set your own climate data for temperature and relative humidity. See also the climate data tutorial for data formats.
