Detailed Description

This class is part of the rbOOmit framework.

TransientRBEvaluation extends RBEvaluation to encapsulate the code and data required to perform "online" RB evaluations for Linear Time Invariant (LTI) transient problems.

We can handle time controls on the RHS as h(t)*f(x, $ \mu $). See Martin Grepl's thesis for more details.

Constructor & Destructor Documentation

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::TransientRBEvaluation::cache_online_residual_terms ( const unsigned int  N)

Helper function for caching the terms in the online residual assembly that do not change in time. (This is only useful when the parameter is fixed in time.)

virtual void libMesh::TransientRBEvaluation::clear ( )
virtual

Clear this TransientRBEvaluation object. Override to also clear the M_q representors

Reimplemented from libMesh::RBEvaluation.

virtual void libMesh::TransientRBEvaluation::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. Override to clear the M_q representors.

Reimplemented from libMesh::RBEvaluation.

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

Reimplemented from libMesh::RBEvaluation.

virtual Real libMesh::TransientRBEvaluation::rb_solve_again ( )

If a solve has already been performed, then we cached some data and we can perform a new solve much more rapidly (with the same parameters but a possibly different initial condition/rhs control).

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.
