Cantera's Interface to the Multiphase chemical equilibrium solver.
Class vcs_MultiPhaseEquil is designed to be used to set a mixture containing one or more phases to a state of chemical equilibrium.
Note, as currently constructed, the underlying ThermoPhase objects are shared between the MultiPhase object and this object. Therefore, mix is not a const argument, and the return parameters are contained in underlying ThermoPhase objects.

vcs_MultiPhaseEquil | ( | Cantera::MultiPhase * | mix, |
int | printLvl | ||
) |
Constructor for the multiphase equilibrium solver.
This constructor will initialize the object with a MultiPhase object, setting up the internal equilibration problem. Note, as currently constructed, the underlying ThermoPhase objects are shared between the MultiPhase object and this object. Therefore, mix is not a const argument, and the return parameters are contained in underlying ThermoPhase objects.
mix | Object containing the MultiPhase object |
printLvl | Determines the amount of printing to stdout that occurs for each call:

size_t component | ( | size_t | m | ) | const |
Return the index of the ith component.

This returns a stoichiometric reaction vector for a single formation reaction for a noncomponent species. There are (nSpecies() - nComponents) formation reactions. Each formation reaction will have a value of 1.0 for the species that is being formed, and the other non-zero coefficients will all involve the components of the mixture.

Object which contains the problem statement.
The problem statement may contain some subtleties. For example, the element constraints may be different than just an element conservation contraint equations. There may be kinetically frozen degrees of freedom. There may be multiple electrolyte phases with zero charge constraints. All of these make the problem statement different than the simple element conservation statement.
