Detailed Description

template<unsigned DIM>
class BidomainProblem< DIM >

Class which specifies and solves a bidomain problem.

The solution vector is of the form: (V_1, phi_1, V_2, phi_2, ......, V_N, phi_N), where V_j is the voltage at node j and phi_j is the extracellular potential at node j.

template<class Archive >

void BidomainProblem< DIM >::LoadExtraArchiveForBidomain	(	Archive &	archive,
		unsigned	version
	)

Used when loading a set of archives written by a parallel simulation onto a single process. Loads data from the given process-specific archive (written by a non-master process) and merges it into our data.

Parameters

archive	the archive to load
version	the archive file version

Note: The process-specific archives currently contain the following data. If the layout changes, then this method will need to be altered, since it hard-codes knowledge of the order in which things are archived.

Stuff known by AbstractCardiacProblem
mpElectrodes->mpBoundaryConditionsContainer

This gets called by AbstractCardiacProblem::LoadExtraArchive when it's done the generic stuff.
