Detailed Description

Base class for unsteady solvers.

Initialises the arterial subdomains in m_vessels and sets up all domain-linking conditions (bifurcations, junctions, merging flows). Detects the network structure and assigns boundary conditons. Also provides the underlying timestepping framework for pulse wave solvers including the general timestepping routines.
