Detailed Description

A class for a 2D "mesh", i.e. a collection of lines connected by corners in a 2D plane which can interact with particles in 2D. The Main purpose is for coupling with 2D FEM (Finley) simulations via escript.

forAllEdgesGet()

template<typename P >

void Mesh2D::forAllEdgesGet	(	P &	cont,
		typename P::value_type(Edge2D::*)() const	rdf
	)

Call a constant member function of Edge2D taking no argument and returning a value for all edges and collect the return values in a container. The container has to be an STL sequence container (vector,list...) or something with the same interface. The template parameter P is a type of container of the return type of the particle member function, not the return type itself.

Parameters

cont	the container
rdf	the particle member function

Parameters

getCornerById()

Corner2D * Mesh2D::getCornerById

(

int

id

)

Get a pointer to a corner with a given ID. If the ID doesn't exist, return NULL

Parameters

id

the id

References NULL.

getEdgeById()

Edge2D * Mesh2D::getEdgeById

(

int

id

)

Get a pointer to a edge with a given ID. If the ID doesn't exist, return NULL

Parameters

id

the id

References NULL.

loadCheckPoint()

void Mesh2D::loadCheckPoint ( istream &  ist )

virtual

load checkpoint data from stream. Re-uses code from meshreader to read in checkpointed meshes

Parameters

ist	the input stream

LoadMesh()

void Mesh2D::LoadMesh	(	const vector< MeshNodeData2D > &	node_vec,
		const vector< MeshEdgeData2D > &	edge_vec
	)

setup 2D mesh from node and edge data

Parameters

node_vec	the node data
edge_vec	the edge data

moveNode()

void Mesh2D::moveNode	(	int	id,
		const Vec3 &	d
	)

move one node by a given amount

Parameters

id	the id of the node
d	the displacement

writeCheckPoint()

void Mesh2D::writeCheckPoint ( ostream &  ost, const string &  delim  ) const

virtual

Write checkpoint data to stream. The mesh data is written in the original mesh file format -> can reuse meshreader to read in checkpointed meshes

Parameters

ost	the output stream
delim	the delimiter

Warning
