Electric car fire in garage

[Theadus]

Hello everyone.
I'm trying to simulate a garage with electric vehicles inside using FDS. The problem I'm encountering is that I can't simulate a fire in the absence of oxygen.
Let me explain: the goal of the simulation is to study the temperatures on the garage roof and structures. When simulating the RHR curve of a generic combustion-engine vehicle, in order for the RHR curve to develop fully, I need to supply oxygen (in the simulation, I created an opening at the bottom of the garage and left the entrance open).
What I'm trying to do is create an RHR curve for the hypothetical electric vehicle, independent of the amount of oxygen, that can develop the thermal power in its entirety, even with the garage closed, or at least with fewer openings.

I'm attaching an FDS file with the RHR curve of the standard vehicle (NIST reference).

Thank you very much, and sorry for the poor English.

PROPANE requires oxygen to burn. If you are putting in more fuel than you have avaiable oxygen, it will not burn. This is a real result. It isn't clear why you would want to force a non-physical amount of heat release inside your domain. This will lead non-physical exposure to the structure. If you feel you must do this you could turn off the exintinction model in FDS to allow you to consume all the available oxygen (see the User's Guide). Beyond that you will need to add oxygen or use a volumetric heat source (i.e. a heat source that does not rely on fuel) which adds its own non-physical aspects.
