void BoundaryConditionsContainer< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::AddDirichletBoundaryCondition	(	const Node< SPACE_DIM > *	pBoundaryNode,
		const AbstractBoundaryCondition< SPACE_DIM > *	pBoundaryCondition,
		unsigned	indexOfUnknown = `0`,
		bool	checkIfBoundaryNode = `true`
	)

Add a Dirichlet boundary condition specifying two parameters, a pointer to a node, and a pointer to a boundary condition object associated with that node.

The destructor for the BoundaryConditionsContainer will destroy the boundary conditions objects.

Parameters

pBoundaryNode	Pointer to a node on the boundary.
pBoundaryCondition	Pointer to the Dirichlet boundary condition at that node.
indexOfUnknown	defaults to 0
checkIfBoundaryNode	defaults to true

		const AbstractBoundaryCondition< SPACE_DIM > *	pBoundaryCondition,
		unsigned	indexOfUnknown = `0`
	)

Add a Neumann boundary condition specifying two parameters, a pointer to a surface element, and a pointer to a boundary condition object associated with that element.

The destructor for the BoundaryConditionsContainer will destroy the boundary conditions objects.

Note that the value of a Neumann boundary condition should specify D * grad(u).n, not just grad(u).n.

Take care if using non-zero Neumann boundary conditions in 1d. If applied at the left hand end you need to multiply the value by -1 to get the right answer.

Parameters

pBoundaryElement	Pointer to an element on the boundary
pBoundaryCondition	Pointer to the Neumann boundary condition on that element
indexOfUnknown	defaults to 0

		bool	applyToMatrix = `true`,
		bool	applyToRhsVector = `true`
	)

Alter the given linear system to satisfy Dirichlet boundary conditions.

If the number of unknowns is greater than one, it is assumed the solution vector is of the form (in the case of two unknowns u and v, and N nodes): solnvec = (U_1, V_1, U_2, V_2, ...., U_N, V_N)

Parameters

rLinearSystem	Linear system on which to apply boundary conditions
applyToMatrix	This optional parameter can be set as false to ensure that the matrix of the linear system is not updated. To be used when the matrix does not change between time steps.
applyToRhsVector	Similarly, whether to apply the changes to the RHS vector (b in Ax=b).

Modifies a linear system to incorporate Dirichlet boundary conditions

The BCs are imposed in such a way as to ensure that a symmetric linear system remains symmetric. For each node with a boundary condition applied, both the corresponding row and column are zero'd and the RHS vector modified to take into account the zero'd column. See #577.

Suppose we have a matrix [a b c] [x] = [ b1 ] [d e f] [y] [ b2 ] [g h i] [z] [ b3 ] and we want to apply the boundary condition x=v without losing symmetry if the matrix is symmetric. We apply the boundary condition [1 0 0] [x] = [ v ] [d e f] [y] [ b2 ] [g h i] [z] [ b3 ] and then zero the column as well, adding a term to the RHS to take account for the zero-matrix components [1 0 0] [x] = [ v ] - v[ 0 ] [0 e f] [y] [ b2 ] [ d ] [0 h i] [z] [ b3 ] [ g ] Note the last term is the first column of the matrix, with one component zeroed, and multiplied by the boundary condition value. This last term is then stored in rLinearSystem.rGetDirichletBoundaryConditionsVector(), and in general form is the SUM_{d=1..D} v_d a'_d where v_d is the boundary value of boundary condition d (d an index into the matrix), and a'_d is the dth-column of the matrix but with the d-th component zeroed, and where there are D boundary conditions

template<class Archive >

void BoundaryConditionsContainer< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::load	(	Archive &	archive,
		const unsigned int	version
	)

inlineprivate

Load this container, but not its content.

Objects loading a boundary conditions container should call LoadFromArchive on the new object immediately after loading it from the archive.

Note that boundary conditions should be saved to the ProcessSpecificArchive, since if a DistributedTetrahedralMesh is used each process will only know a portion of the mesh, and hence a portion of the boundary conditions.

Extra care needs to be taken when migrating to ensure that boundary conditions are loaded appropriately. See BidomainProblem::LoadExtraArchiveForBidomain and AbstractCardiacProblem::LoadExtraArchive for examples.

Parameters

archive
version

template<class Archive >

void BoundaryConditionsContainer< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::LoadFromArchive	(	Archive &	archive,
		AbstractTetrahedralMesh< ELEMENT_DIM, SPACE_DIM > *	pMesh
	)

inline

Load a collection of boundary conditions from an archive.

Note: We assume this collection is empty prior to being called. If it is not, any boundary conditions already present may get replaced by conditions loaded from the archive, which may lead to a memory leak.

This method only loads data if mLoadedFromArchive is false, to allow for multiple pointers to the same container to be handled correctly. It sets mLoadedFromArchive when done.

Parameters

archive	the archive to load from
pMesh	the mesh to use to resolve Node and BoundaryElement indices

template<class Archive >

void BoundaryConditionsContainer< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::MergeFromArchive	(	Archive &	archive,

	)

Load extra boundary conditions from an archive to add to this collection.

Multiple pointers to the same container need to be handled by the caller - we assume there will be conditions to load. Sets mLoadedFromArchive when done.

Parameters

archive	the archive to load from
pMesh	the mesh to use to resolve Node and BoundaryElement indices

Check that we have boundary conditions defined everywhere on mesh boundary.

We iterate over all surface elements, and check either that they have an associated Neumann condition, or that each node in the element has an associated Dirichlet condition.

Returns: true iff all boundaries have boundary conditions defined.
