Detailed Description

The framework connects the equation descriptions with the discretization. It consists of three parts:

• Interfaces (include/ryujin/interface): abstract base classes that are independent of the equation. The driver and the discretization only use these.
• Concepts (include/ryujin/concept): the C++20 concepts a hyperbolic description (HD) or a parabolic description (PD) has to satisfy.
• Typed implementations (include/ryujin/typed and include/ryujin/stub): implementations of the interfaces that are templated on HD and PD.

At run time, the objects are created and owned as follows. The ryujin executable (source/main.cc) selects one of the registered equations and the dimension with the run time parameters "equation" and "dimension"; the equation constructs the Simulation and the TaskComposition. A client program constructs them directly:
