Detailed Description

LOCA eigenvalue driver using Anasazi

This class provides a concrete implementation of the computeEigenvalues() method of the LOCA::Continuation::AbstractGroup using Anasazi, the generic Trilinos eigensolver. Eigenvalues of the Jacobian and generalized eigenvalues of the Jacobian/mass matrix are supported using shift-invert, as well as generalized Cayley transformations.

NOX::Abstract::Group::ReturnType LOCA::Continuation::AnasaziGroup::computeEigenvalues (  NOX::Parameter::List &  params  )  [virtual]

Computes leading eigenvalues/eigenvectors using Anasazi package. Driver for eigensolver, including preprocessing of parameters, generating initial vector, calling eigensolver, and post-processing of the results. Reimplemented from LOCA::Continuation::AbstractGroup. Reimplemented in LOCA::LAPACK::Group.
