Member Data Documentation

unsigned int libMesh::RBEIMAssembly::_basis_function_index
private

The EIM basis function index (from rb_eim_eval) for this assembly object.

Definition at line 101 of file rb_eim_assembly.h.

ReferenceCounter::Counts libMesh::ReferenceCounter::_counts
staticprotectedinherited
bool libMesh::ReferenceCounter::_enable_print_counter = true
staticprotectedinherited

Flag to control whether reference count information is printed when print_info is called.

Definition at line 137 of file reference_counter.h.

Referenced by libMesh::ReferenceCounter::disable_print_counter_info(), libMesh::ReferenceCounter::enable_print_counter_info(), and libMesh::ReferenceCounter::print_info().

std::vector< QBase* > libMesh::RBEIMAssembly::_fe_qrule
private

We also store the quadrature rule associated with each FE object.

Definition at line 120 of file rb_eim_assembly.h.

std::vector< FEBase* > libMesh::RBEIMAssembly::_fe_var
private

We store an FE object for each variable in _rb_eim_con. This is used in evaluate_basis_function. Note that by storing the FE objects (rather than recreating them each time) we benefit from caching in fe.reinit().

Definition at line 115 of file rb_eim_assembly.h.

AutoPtr< NumericVector<Number> > libMesh::RBEIMAssembly::_ghosted_basis_function
private

The basis function that we sample to evaluate the empirical interpolation approximation. This will be a GHOSTED vector to facilitate interpolation in the case of multiple processors.

Definition at line 108 of file rb_eim_assembly.h.

Threads::spin_mutex libMesh::ReferenceCounter::_mutex
staticprotectedinherited

Mutual exclusion object to enable thread-safe reference counting.

Definition at line 131 of file reference_counter.h.

Threads::atomic< unsigned int > libMesh::ReferenceCounter::_n_objects
staticprotectedinherited

The number of objects. Print the reference count information when the number returns to 0.

Definition at line 126 of file reference_counter.h.

Referenced by libMesh::ReferenceCounter::n_objects(), libMesh::ReferenceCounter::ReferenceCounter(), and libMesh::ReferenceCounter::~ReferenceCounter().

RBEIMConstruction& libMesh::RBEIMAssembly::_rb_eim_con
private

The RBEIMConstruction object that this RBEIMAssembly is based on.
