forAllTrianglesGet()

template<typename P >

void TriMesh::forAllTrianglesGet	(	P &	cont,
		typename P::value_type(Triangle::*)() const	rdf
	)

Call a constant member function of Triangle taking no argument and returning a value for all Triangles 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

rdf	the particle member function

Here is the caller graph for this function:

getTriangleById()

Triangle * TriMesh::getTriangleById

(

int

id

)

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

Parameters

id

the id

References NULL.

hasMovedBy()

bool TriMesh::hasMovedBy

(

double

dist

)

check if any point in the mesh has moved by at least the given distance

Parameters

dist	the distance

Here is the caller graph for this function:

LoadMesh()

void TriMesh::LoadMesh	(	const vector< MeshNodeData > &	node_vec,
		const vector< MeshTriData > &	tri_vec
	)

setup the triangle mesh from node,edge and triangle data

Parameters

node_vec	the node data
tri_vec	the triangle data

Here is the caller graph for this function:

moveNode()

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

Move a node in the mesh. If the node with the given Id isn't in the mesh, nothing happens

Parameters

id	the id of the node
d	the displacement

References esys::lsm::bpu::iter().

Here is the call graph for this function:

resetCurrentDisplacement()

void TriMesh::resetCurrentDisplacement

(

reset displacement since last neighbor search

writeCheckPoint()

void TriMesh::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

References esys::lsm::bpu::iter().

Here is the call graph for this function:

zeroForces()

void TriMesh::zeroForces

(

)

zero all forces on the mesh. Currently forces are only on triangles
