Settings for Steckler Room Fire Validation
Set heat transfer coefficients for the surfaces that represent the walls and ceiling.
In the Steckler room fire experiment, the walls and ceiling are composed of conduction brick of thickness 0.1m and conductivity of 0.69W/m-K. Set an effective heat transfer coefficient of 6.9 W/m^2-K for each of the five shell surfaces representing the walls and ceiling of the room.
