air ambient temperature

[BVsimulator]

hello members,

Does anybody know, how i can set an ambient temperature for a room? e.g. i want to set a ambient temperature for an industrial hall (80 m x 40 m x8 m) with a value of 20 °C.

In the description of Pyrosim stands in the chapter surfaces: Inerts, This surface remains fixed at the ambient temperature. What value has here the ambient temperature and can i change it?

thx

best regards,

FDS's default ambient temperature is 20 C. You can verify this in the FDS Users Guide, in section 6.4 Miscellaneous Parameters: The MISC Namelist Group - the variable is TMPA.

In PyroSim, if you wanted something other than 20 C, you can set the ambient temperature for the entire model in the Simulation Parameters dialog:

1. On the FDS menu, click Simulation Paramters
2. Select the Environment tab
3. Click to enable Ambient Temperature, then enter a value
