#include <VPStandardStateTP.h>
This is a filter class for ThermoPhase that implements some preparatory steps for efficiently handling a variable pressure standard state for species.
Several concepts are introduced. The first concept is there are temporary variables for holding the species standard state values of Cp, H, S, G, and V at the last temperature and pressure called. These functions are not recalculated if a new call is made using the previous temperature and pressure.
To support the above functionality, pressure and temperature variables, m_Plast_ss and m_Tlast_ss, are kept which store the last pressure and temperature used in the evaluation of standard state properties.
This class is usually used for nearly incompressible phases. For those phases, it makes sense to change the equation of state independent variable from density to pressure. The variable m_Pcurrent contains the current value of the pressure within the phase.

Calculate the density of the mixture using the partial molar volumes and mole fractions as input.
The formula for this is
\[ \rho = \frac{\sum_k{X_k W_k}}{\sum_k{X_k V_k}} \]
where \( X_k \) are the mole fractions, \( W_k \) are the molecular weights, and \( V_k \) are the pure species molar volumes.
Note, the basis behind this formula is that in an ideal solution the partial molar volumes are equal to the pure species molar volumes. We have additionally specified in this class that the pure species molar volumes are independent of temperature and pressure.
NOTE: This function is not a member of the ThermoPhase base class.

Initialize the ThermoPhase object after all species have been set up.
This method is provided to allow subclasses to perform any initialization required after all species have been added. For example, it might be used to resize internal work arrays that must have an entry for each species. The base class implementation does nothing, and subclasses that do not require initialization do not need to overload this method. Derived classes which do override this function should call their parent class's implementation of this function as their last action.
When importing from an AnyMap phase description (or from a YAML file), setupPhase() adds all the species, stores the input data in m_input, and then calls this method to set model parameters from the data stored in m_input.
