Detailed Description

template<int N, typename T>
class LagrangianComm< N, T >

Base class Lagrangian communicator for the Eulerian-Lagrangian coupling.

Parameters:

	N	is the space dimension. 1, 2 and 3 are supported.
	T	is the floating point number type.

Implements the common functionality for boundaries and shells.

Constructor & Destructor Documentation

template<int N, typename T >

LagrangianComm< N, T >::LagrangianComm	(	const MPI_Comm	comm,
		const MPI_Comm	lagrangian,
		const int	eulerianSize,
		const int	eulerianRoot,
		VertexIdentifierStyle	vertexIdentifierStyle
	)			[inline]

Construct from the communicators and Eulerian information.

Parameters:

	comm	is the communicator that contains the Eulerian and Lagrangian processors.
	lagrangian	is the Lagrangian communicator. It is duplicated to avoid message conflicts.
	eulerianSize	is the number of Eulerian processors.
	eulerianRoot	is the rank of the Eulerian root in comm.
	vertexIdentifierStyle	is either LocalIndices or GlobalIdentifiers.

Member Function Documentation

template<int N, typename T >

void LagrangianComm< N, T >::sendMesh	(	const int	numNodes,
		const void *	identifiers,
		const void *	positions,
		const void *	velocities,
		const int	numFaces,
		const void *	connectivities
	)

Post sends for sending the local Lagrangian mesh to the relevant Eulerian processors.

Parameters:

	numNodes	is the number of nodes in the mesh.
	identifiers	are the global mesh node identifiers.
	positions	are the meh node positions. This is an array of N-tuples of numbers. Each N-tuple is a Cartesian point.
	velocities	are the mesh node velocities.
	numFaces	is the number of faces in the mesh.
	connectivities	describes the connectivites of the nodes to form faces. This is an array of N-tuples of integers. Each N-tuple represents on indexed face (line segment in 2-D, triangle in 3-D). If the vertex identifier style is LocalIndices, then each index is in the range [0..numFaces). If the style is GlobalIdentifers, then each element of connectivities is listed in the identifiers array.
