Detailed Description

A class to initialize libMesh.

This class provides routines for initializing and finalizing libmesh. Note: this class is not thread safe yet.

Constructor & Destructor Documentation

initializeLibMesh() [1/2]

AMP::Mesh::initializeLibMesh::initializeLibMesh ( const AMP_MPI &  comm )

explicit

Constructor that inializes libmesh on the given communicator. Note: libmesh can only be initialized on one comm at a given time. This function can be called more than once. If the the comms share the same comm, then this function will succeed. It the comms are different, then this function will throw an error. If a different comm is needed, then the user needs to call finalize first.

~initializeLibMesh()

AMP::Mesh::initializeLibMesh::~initializeLibMesh

(

)

Deconstructor that finalizes libmesh. This allows libmesh to be reinitialized on a new comm, and frees any memory in use by libmesh.

Member Function Documentation

canBeInitialized()

static bool AMP::Mesh::initializeLibMesh::canBeInitialized ( const AMP_MPI &  comm )

static

Function to check if libmesh can be initialized with the given comm. If this function returns true, then initializeLibMesh::initialize can be safely called with the given comm. Otherwise, initializeLibMesh::finalize must be called first.

isInitialized()

static bool AMP::Mesh::initializeLibMesh::isInitialized ( )

static

Function to check if libmesh has been initialized for any communicator (are there any copies of the class that have not been destroyed)
