Summary: Initialize Properties for Natural Convection Simulations.
Flag
use_property_ref_temp A
A = 1: (On) = the initial temperature of the material is set to the property environment temperature
A = 0: (Off) = the initial temperature is set from the specified boundary condition
Description
By default, initial fluid (air) property values in natural convection analyses are computed based on the lowest specified temperature boundary condition. This is the desired behavior for simulating cooling of a device by natural convection.
For situations in which the device is heated by natural convection, it is better to initialize the fluid (air) properties based on the Environment temperature. To do this enable this flag.
