virtual libMesh::RBEIMEvaluation::~RBEIMEvaluation ( )

virtual

Destructor.

Member Function Documentation

assert_file_exists()

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

protectedinherited

Helper function that checks if file_name exists.

attach_parametrized_function()

void libMesh::RBEIMEvaluation::attach_parametrized_function

(

RBParametrizedFunction *

pf

)

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

build_eim_theta()

virtual std::unique_ptr<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.

clear()

virtual void libMesh::RBEIMEvaluation::clear ( )

overridevirtual

Clear this object.

Reimplemented from libMesh::RBEvaluation.

clear_riesz_representors()

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.
