Detailed Description

Derived model class within the surrogate model branch for managing a truth model alongside approximation models of varying fidelity.

The EnsembleSurrModel class manages subordinate models of varying fidelity. The class contains a truth model and an array of approximation models, where each model form may also contain a set of solution levels (space/time discretization, convergence tolerances, etc.).

Member Function Documentation

initialize_mapping()

bool initialize_mapping ( ParLevLIter  pl_iter )

protectedvirtual

Inactive variables must be propagated when an EnsembleSurrModel is employed by a sub-iterator (e.g., OUU with MLMC or MLPCE). In current use cases, this can occur once per sub-iterator execution within Model::initialize_mapping().

Reimplemented from Model.

finalize_mapping()

bool finalize_mapping ( )
