Abstract nonlinear solver method interface.
Defines the type of access methods into the iterative nonlinear solvers.
|
pure virtual |
Resets the solver for another solve. This resets the counters and status only. Uses the final solution from the last solve as the initial guess for the next solve.
NOTE: All NOX solvers will call reset() automatically at teh beginning of the solve() method. We add the reset() method to the solver interface for the application to call in case the application needs to reset counters and status manually before the next call to solve() is made.
Implemented in NOX::Solver::InexactTrustRegionBased, NOX::Solver::TensorBased, NOX::Solver::TrustRegionBased, NOX::Multiphysics::Solver::FixedPointBased, NOX::Solver::AndersonAcceleration, NOX::Solver::LineSearchBased, NOX::Multiphysics::Solver::Generic, NOX::Multiphysics::Solver::Manager, LOCA::Solver::Wrapper, NOX::Solver::PseudoTransient, and NOX::Solver::SingleStep.

pure virtual |
Solve the nonlinear problem and return final status.
By "solve", we call iterate() until the NOX::StatusTest value is either NOX::StatusTest::Converged or NOX::StatusTest::Failed.
Implemented in NOX::Solver::InexactTrustRegionBased, NOX::Solver::TensorBased, NOX::Solver::TrustRegionBased, NOX::Multiphysics::Solver::FixedPointBased, NOX::Solver::AndersonAcceleration, NOX::Solver::LineSearchBased, LOCA::Solver::Wrapper, NOX::Multiphysics::Solver::Manager, NOX::Solver::PseudoTransient, and NOX::Solver::SingleStep.
