A data structure containing output fields that can be filled by the evaluate() function of an EquationOfState model. It contains those properties of the MaterialModelOutputs that are connected to the equation of state (or the thermodynamic properties). Output values are computed separately for each composition and phase.
Accordingly, the vectors are the values for each compositional field and individual phase at one specific location.

| aspect::MaterialModel::EquationOfStateOutputs< dim >::EquationOfStateOutputs | ( | const unsigned int | n_individual_compositions_and_phases | ) |
Constructor. Initialize the various arrays of this structure with the given number of compositions and phases.
| n_individual_compositions_and_phases | The number of vector quantities for which input will be provided, and outputs should be filled. Note that this number does not have to be the number of compositions, it can be smaller (if some compositional fields do not represent volumetric compositions, but tracked quantities like strain) or larger (if there is a background field, or some compositions have several high-pressure phases). It is the responsibility of the material model and equation of state object to interpret the entries consistently. |
| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::densities |
Density values for each composition and phase.

| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::thermal_expansion_coefficients |
Thermal expansion coefficients for each composition and phase. It is defined as \(\alpha = - \frac{1}{\rho} \frac{\partial\rho}{\partial T}\)
Definition at line 73 of file interface.h.
| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::specific_heat_capacities |
Specific heat for each composition and phase.
Definition at line 78 of file interface.h.
| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::compressibilities |
Compressibility for each composition and phase. The compressibility is defined as \(\kappa = \frac{1}{\rho} \frac{\partial\rho}{\partial p}\).

| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::entropy_derivative_pressure |
The product of the change of entropy \(\Delta S\) at a phase transition and the derivative of the phase function \(X=X(p,T,\mathfrak c,\mathbf x)\) with regard to pressure for each composition and phase.
Definition at line 91 of file interface.h.
| std::vector<double> aspect::MaterialModel::EquationOfStateOutputs< dim >::entropy_derivative_temperature |
The product of (minus) the change of entropy \(-\Delta S\) at a phase transition and the derivative of the phase function \(X=X(p,T,\mathfrak c,\mathbf x)\) with regard to temperature for each composition and phase.
