Thermodynamic States and Properties, uniform-system state daemons

Launch the Daemon by Selecting a Material Model.

PC Model		The phase-change (PC) model is based on the saturation and super-heated tables and is generally quite accurate. Sub-cooled liquid is modeled with the compressed-liquid sub-model, except for H2O*, which uses compressed liquid table for high accuracy. Working fluids such as H2O, R-12, NH3, R-134a, N2, CO2, etc., should be treated as PC fluids if there is any possibility of a phase transformation.
SL Model		Constant density and specific heats (c_p=c_v=c) characterize the solid/liquid (SL) model. Beside a wide selection to choose from, a new solid or liquid can be created by assigning custom material properties.
Gases:	PG Model	The perfect gas (PG) model obeys the ideal gas equation (pv=RT). However, the specific heats are assumed constants. Beside a wide selection, new gases can be created by assigning custom material properties. A perfect gas can be considered as a simplified ideal gas.
	IG Model	An ideal gas (IG) model obeys the ideal gas equation (pv=RT). Specific heats are temperature dependent. As a result the IG model is more accurate than the PG model when variation in temperature is large. Choose from an wide selection of gases.
	RG Model	Based on the generalized compressibility chart (pv=ZRT), the real gas (RG) model can handle a large number of fluids in their liquid, vapor or gaseous states. But generality comes at the expense of accuracy.
	Binary Mixtures The mixture of two gases, A and B, is expressed in terms of the mass or mole fraction of gas-A.	PG+PG Model	IG+IG Model	RG+RG Model	MoistAir (PG+PG+PC)
	General Mixtures Mixture can contain any number of species from 1 to n (n=60+).	n-PG Model		n-IG Model
