Detailed Description

Anasazi eigensolver strategy.

This class implements an eigensolver strategy using the generic Trilinos eigensolver package Anasazi. Since Anasazi is a generic solver, this strategy will work with any group implementation. This strategy references the following parameters passed through the eigenParams argument to the constructor:


Constructor & Destructor Documentation

LOCA::Eigensolver::AnasaziStrategy::AnasaziStrategy const Teuchos::RefCountPtr< LOCA::GlobalData > &  global_data,
const Teuchos::RefCountPtr< LOCA::Parameter::SublistParser > &  topParams,
const Teuchos::RefCountPtr< NOX::Parameter::List > &  eigenParams
 

Constructor.

Parameters:
global_data [in] Global data object
topParams [in] Parsed top-level parameter list. Used to obtain linear-solver parameters and to instantiate sorting strategy.
eigenParams [in] Eigensolver parameters as described above. solver.
