Constructor & Destructor Documentation

BoundaryConditions()

BoundaryConditions::BoundaryConditions	(	const std::string	bc_id,
		Mesh &	mesh
	)

Initialise data.

Parameters

bc_id	The identifier for the boundary condition (D, N or Mx)
mesh	reference to the mesh

Member Function Documentation

n_dir_edges()

const size_t BoundaryConditions::n_dir_edges ( ) const

inline

Returns the number of Dirichlet edges.

n_dir_vertices()

const size_t BoundaryConditions::n_dir_vertices ( ) const

inline

Returns the number of Dirichlet vertices.

name()

const std::string BoundaryConditions::name ( ) const

inline

Returns the complete name of the boundary condition.

reorder_edges()

void BoundaryConditions::reorder_edges

(

const std::string

pos = "end"

)

Re-order edges of the mesh to put the Dirichlet edges at the position "pos" (=end or start)

reorder_vertices()

void BoundaryConditions::reorder_vertices

(

const std::string

pos = "end"

)

Re-order vertices of the mesh to put the Dirichlet vertices at the position "pos" (=end or start)

type() [1/2]

const std::string BoundaryConditions::type

(

const Edge &

edge

)

const

Test the boundary condition of an edge.

Returns

"dir" or "neu" depending if the edge is a Dirichlet or Neumann boundary condition, as determined by m_bc_id below. For an internal edge, returns "int". m_bc_id = "D": all edges are Dirichlet m_bc_id = "N": all edges are Neumann m_bc_id = "Mx" (x=0,1,...): various types of mixed boundary conditions, some edges will be Dirichlet and some will be Neumman.

Parameters

edge	Edge on which to check the boundary condition

type() [2/2]

const std::string BoundaryConditions::type

(

const Vertex &

vertex

)

const

Test the boundary condition of a vertex.

Parameters

vertex

Vertex on which to check the boundary condition
