2 different ambient air temperatures

[BVsimulator]

It is possible to set more than one ambient air temperature? Because I want to create a szenario, where the temperature in the building is e.g. 20 degree (C°) and outside of the building e.g. 35 degree (C°).

When it is possible, then how I can set this attitudes.

Thanks

best regards,
BVsimulator

The feature you are looking for is FDS's INIT record. It lets you define the initial temperature within a region. In PyroSim, they are referred to as "Initial Regions".

On the Model menu, click New Init Region...

Hi.
I hope I'm not asking a very silly question.
But I cannot find the "New Init Region" command.
I have the 2010.1.0928 Pyrosim Version.
I thank you in advance.

We added support for the INIT record in PyroSim 2010.2.1114. (release notes)

Once you've got that version, you can find the option in the Model menu (see attached screen grab).

If you don't want to update PyroSim, I think the INIT namelist works well in the additional records section.
