## Properties / Property System
In DuMuX, the property system provides a flexible way to configure simulations at compile time. Properties are structs that define types which determine how different parts of the framework work together. The system ensures a consistent class hierarchy by allowing users to inherit from predefined models and customize specific properties as needed.
Users typically collect their property customizations in a `properties.hh` file specific to their simulation setup. For more detailed and technical information about the property system, see @ref Properties.
