Detailed Description

The sensitivity derivatives of a chemical equilibrium state.

This class stores the sensitivity derivatives of a chemical equilibrium state. These are partial derivatives of the species amounts with respect to input variables, such as temperature, pressure, amounts of the elements. If the chemical equilibrium state is computed with other given conditions, for example, given volume and internal energy, derivatives with respect to these input conditions will be available. These sensitivity derivatives are important for implicit numerical methods, since they enable faster convergence rates.
