Methods in the saftvrqmie class
ThermoPack - 2.1.0
The saftvrmie class, found in addon/pycThermopack/thermopack/saftvrqmie.py, is the interface to the
SAFT-VRQ Mie Equation of State.
NOTE: This class inherits the saftvrmie class, and thereby has
access to the model control and utility methods found there. The saftvrmie class inherits
the saft class, which in turn inherits the thermo class.
This class implements utility methods specific to the SAFT-VRQ Mie EoS.

__init__(self, comps=None, feynman_hibbs_order=1, additive_hard_sphere_reference=False, parameter_reference='Default', minimum_temperature=None)
Initialize SAFT-VRQ Mie model in thermopack Equation of state and force fields for Feynman–Hibbs-corrected Mie fluids. I. Application to pure helium, neon, hydrogen, and deuterium (doi.org/10.1063/1.5111364 Equation of state and force fields for Feynman–Hibbs-corrected Mie fluids. II. Application to mixtures of helium, neon, hydrogen, and deuterium (doi.org/10.1063/1.5136079) If no components are specified, model must be initialized for specific components later by direct call to ‘init’ Model can at any time be re-initialized for new components or parameters by direct calls to ‘init’
