Constructor & Destructor Documentation

libMesh::RBEvaluation::RBEvaluation ( const Parallel::Communicator &comm  LIBMESH_CAN_DEFAULT_TO_COMMWORLD)

Constructor.

virtual libMesh::RBEvaluation::~RBEvaluation ( )
virtual

Destructor.

Member Function Documentation

virtual void libMesh::RBEvaluation::clear ( )
virtual

Clear this RBEvaluation object. Delete the basis functions and clear and extra data in subclasses.

Reimplemented from libMesh::RBParametrized.

Reimplemented in libMesh::RBEIMEvaluation, and libMesh::TransientRBEvaluation.

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

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.

const Parallel::Communicator& libMesh::ParallelObject::comm ( ) const
inlineinherited
Returns
a reference to the Parallel::Communicator object used by this mesh.

Perform online solve with the N RB basis functions, for the set of parameters in current_params, where 0 <= N <= RB_size.

Returns
the (absolute) error bound associated with the RB approximation. With an empty RB space (N=0), our RB solution is zero, but we still obtain a meaningful error bound associated with the forcing terms.
