Special contributions

Derivative

class simu.app.thermo.contributions.special.Derivative

This auxiliary contribution provides the derivative of an arbitrary property with respect to an independent (state) variable. This can for instance be used to equip a thermodynamic model with extra temperature derivatives for calculating heat capacity or partial molar enthalpy as canonical properties.

The contribution requires an option dictionary with the following entries:

• x: The name of the independent property \(x\)

• y: The name of the dependent property \(y\)

The derivative \(\partial y/\partial x\) will be provided as f"d{options['y']}_d{options['x']}".
