bool Boundaries::isValid_pT	(	Pressure	p,
		Temperature	T,
		bool	throw_me = false
	)			[static]

Overall pressure/temperature validity check.

Check that the pressure and temperature are within limits, and optionally throw an error if they are out of bounds.

bool Boundaries::isRegion1_pT	(	Pressure	p,
		Temperature	T,
		bool	throw_me = false
	)			[static]

Check for a pressure/temperature being in the saturated zone (within some tolerance).

Check that the temperature and pressure given indicate saturated conditions.

Note that the STM_SATURATION_TOL is used to allow a small region of error on this test.

Parameters:

	p	pressure / [MPa]
	T	temperature / [K] Test for a pressure/temperature being in Region 1
	p	pressure / [MPa]
	T	temperature / [K]]
	throw_me	Throw an error if point is not in Region 1

bool Boundaries::isRegion2_pT	(	Pressure	p,
		Temperature	T,
		bool	throw_me = false
	)			[static]

Test for a pressure/temperature being in Region 2.

Parameters:

	p	pressure / [MPa]
	T	temperature / [K]]
	throw_me	Throw an error if point is not in Region 2
