Constructor & Destructor Documentation

libMesh::RBEIMEvaluation::RBEIMEvaluation ( const libMesh::Parallel::Communicator &comm_in  LIBMESH_CAN_DEFAULT_TO_COMMWORLD)

Constructor.

virtual libMesh::RBEIMEvaluation::~RBEIMEvaluation ( )
virtual

Destructor.

Member Function Documentation

void libMesh::RBEvaluation::assert_file_exists ( const std::string &  file_name)
protectedinherited

Helper function that checks if file_name exists.

void libMesh::RBEIMEvaluation::attach_parametrized_function ( RBParametrizedFunction pf)

Attach the parametrized function that we will approximate using the Empirical Interpolation Method.

virtual UniquePtr<RBTheta> libMesh::RBEIMEvaluation::build_eim_theta ( unsigned int  index)
virtual

Build a theta object corresponding to EIM index index. The default implementation builds an RBEIMTheta object, possibly override in subclasses if we need more specialized behavior.

virtual void libMesh::RBEIMEvaluation::clear ( )
virtual

Clear this object.

Reimplemented from libMesh::RBEvaluation.

virtual void libMesh::RBEvaluation::clear_riesz_representors ( )
virtualinherited

Clear all the Riesz representors that are used to compute the RB residual (and hence error bound). This is useful since once we complete the Greedy we may not need the representors any more.

Reimplemented in libMesh::TransientRBEvaluation.

Performs read_in_vectors for a list of directory names and data names. Reading in vectors requires us to renumber the dofs in a partition-independent way. This function only renumbers the dofs once at the start (and reverts it at the end), which can save a lot of work compared to renumbering on every read.
