External Conditions dialog box (Flow/ESC/Multiphysics)

Modeling Object
Name	Sets a meaningful name for the modeling object.
Label	Sets a unique numeric identifier for the modeling object.
Properties
Description	Sets a description for the modeling object.
Temperature and Humidity
Temperature and Humidity	Specifies the temperature and humidity of the fluid, which enters the fluid domain. Fluid leaving the domain is unaffected.AmbientUses the definitions for temperature and humidity of fluid entering the fluid domain as specified in the Ambient Conditions page in the Solution dialog box.SpecifyLets you define the conditions for flow entering the 3D fluid domain for specific locations in your model. You specify a constant or time varying temperature in the Temperature Value box.For more information, see Additional magnitude options.
Humidity	Appears when Temperature and Humidity is set to Specify.Specifies the humidity of air entering the fluid domain.NoneNo humidity is entering the fluid domain.RelativeDefines humidity using the ratio of the partial pressure of water vapor in the mixture to the saturated vapor pressure of water at a given temperature. You specify the relative humidity of the air entering at the chosen location as a percentage in the Relative Humidity (%) box.For more information, see Additional magnitude options.SpecificDefines the humidity using the ratio of the mass of the water vapor to the mass of the dry air that you specify in the Water Vapor to Dry Air Mass Ratio box.For more information, see Additional magnitude options.When you use the parallel flow solver, you can specify Relative Humidity (%) or Water Vapor to Dry Air Mass Ratio as a function of time.
