Description

Constraint solvers converting primary to secondary variables.

Constraint solvers are auxiliary tools to make sure that a fluid state is consistent with some thermodynamic constraints. All constraint solvers specify a well defined set of input variables and make sure that the resulting fluid state is consistent with a given set of thermodynamic equations. Constraint solvers connect the thermodynamic relations expressed by fluid systems with the thermodynamic quantities stored by fluid states. Using them is not mandatory for models, but given the fact that some thermodynamic constraints can be quite complex to solve, sharing this code between models makes sense.
