Detailed Description

template<int N, typename T = double>
class EulerianCommShell< N, T >

Eulerian communicator for the Eulerian-Lagrangian coupling for a shell.

Parameters:

	N	is the space dimension. 2 and 3 are supported.
	T	is the floating point number type. By default it is double.

This class is instantiated in each Eulerian (fluid) processor. The relevant portions of the solid shell are received from the solid processors with either receiveMesh(const BBox& domain) or receiveMesh(const Number* domain) followed by a call to waitForMesh().

One can access the node positions with either getPositions() or getPositionsData(); the node velocities can be access with getVelocities() or getVelocitiesData(); the face normals and centroids can be accessed with getFaceNormals() and getFaceCentroids(). For each face that lies within this processor's computational domain, it must set the pressure difference across the face. (The face is in the computational domain if the centroid is in the domain.) The pressure differences may be manipulated through getPressures() or getPressuresData().

After the pressures have been set, they are sent to the relevant Lagrangian processors with sendPressure() and waitForPressure().

template<int N, typename T = double>

EulerianCommShell< N, T >::EulerianCommShell	(	const MPI_Comm	comm,
		const MPI_Comm	eulerian,
		const int	lagrangianSize,
		const int	lagrangianRoot,
		VertexIdentifierStyle	vertexIdentifierStyle
	)			`[inline]`

Construct from the communicators and Lagrangian info.

Parameters:

	comm	is the communicator that contains the Eulerian and Lagrangian processors.
	eulerian	is the Eulerian communicator. It is duplicated to avoid message conflicts.
	lagrangianSize	is the number of Lagrangian processors.
	lagrangianRoot	is the rank of the Lagrangian root in `comm`.
	vertexIdentifierStyle	is either LocalIndices or GlobalIdentifiers.
