Detailed Description

Base class for unsteady solvers.

Provides the underlying timestepping framework for shallow water flow solvers including the general timestepping routines. This class is not intended to be directly instantiated, but rather is a base class on which to define shallow water solvers, e.g. SWE, Boussinesq, linear and nonlinear versions.

For details on implementing unsteady solvers see sectionADRSolverModuleImplementation
