Detailed Description

Public interface for kinetics managers.

This class serves as a base class to derive 'kinetics managers', which are classes that manage homogeneous chemistry within one phase, or heterogeneous chemistry at one interface. The virtual methods of this class are meant to be overloaded in subclasses. The non-virtual methods perform generic functions and are implemented in Kinetics. They should not be overloaded. Only those methods required by a subclass need to be overloaded; the rest will throw exceptions if called.

When the nomenclature "kinetics species index" is used below, this means that the species index ranges over all species in all phases handled by the kinetics manager.

◆ kineticsSpeciesIndex() [1/3]

size_t kineticsSpeciesIndex ( size_t  k,
size_t  n 
) const
inline

The location of species k of phase n in species arrays.

Kinetics manager classes return species production rates in flat arrays, with the species of each phases following one another, in the order the phases were added. This method is useful to find the value for a particular species of a particular phase in arrays returned from methods like getCreationRates that return an array of species-specific quantities.

Example: suppose a heterogeneous mechanism involves three phases. The first contains 12 species, the second 26, and the third 3. Then species arrays must have size at least 41, and positions 0 - 11 are the values for the species in the first phase, positions 12 - 37 are the values for the species in the second phase, etc. Then kineticsSpeciesIndex(7, 0) = 7, kineticsSpeciesIndex(4, 1) = 16, and kineticsSpeciesIndex(2, 2) = 40.

Parameters
kspecies index
nphase index for the species
