@brief Constitutive relations for fluids, solids, fluid-matrix interactions, and more
@details Constitutive relations formalize the functional dependence among physical variables, thereby providing the missing equations to close systems. Some constitutive relations, in particular if they are ad-hoc (e.g. Hooke's law) or empirical
and not derived from basic principles, are also called material laws.
Implementations of the functional relationships available in DuMu<sup>x</sup> are collected in the folder `dumux/material`.
Most implementations follow one of the following paradigms
* free functions (in nested namespaces),
* stateless classes with static member functions where all parameters are function arguments,
* statefull classes that contain parameters that need to be initialized.
Stateless, purely static classes have the advantage that only the class type needs to be known to
the class using them. Statefull classes need to be instantiated
and the instantiated object is passed to the consumer class.

@details Components provide the thermodynamic relations for the liquid, gaseous and/or solid state of a single
chemical species or a _fixed_ mixture of species. Fluid systems use components to compute thermodynamic quantities of phases. An example would be the dynamic viscosity at different temperatures and pressures.

@brief Constitutive relations such as pc-Sw relations, kr-Sw relations, effective diffusion coefficients, friction laws
@details Constitutive models for interaction of fluids and solids. The relations depend on the fluid state as well as material parameters of the matrix. For example, in porous media theory, the effective heat conductivity depends on the solid heat conductivity, the fluid heat conductivity, as well as the porosity of the solid and the fluid saturation.
@brief Constitutive models for interaction of fluids and solids
@details This module includes constitutive relations such as pc-Sw relations, kr-Sw relations, effective diffusion coefficients, friction laws. The relations depend on both the fluid state as well as material parameters of the solid matrix. For example, in porous media theory, the effective heat conductivity depends on the solid heat conductivity, the fluid heat conductivity, as well as the porosity of the solid and the fluid saturation.
