Detailed Description

Manager class to control the instantiation of the objects derived from the NOX::Solver::Generic object.

Parameters

The following entries may be specified in the parameter list.

• "Nonlinear %Solver" - Name of the solver method. Valid choices are
  • "Line Search Based" (NOX::Solver::LineSearchBased) [Default]
  • "Trust Region Based" (NOX::Solver::TrustRegionBased)

Deprecated:

The "Nonlinear %Solver" choices "Newton" and "Line Search" are deprecated and revert to "Line Search Based". Likewise, the choice "Trust Region" is deprecated and reverts to "Trust Region Based".

Member Function Documentation

void NOX::Multiphysics::Solver::Manager::reset ( )

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.

Implements NOX::Solver::Generic.

Referenced by Manager().

NOX::StatusTest::StatusType NOX::Multiphysics::Solver::Manager::solve ( )

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.

Implements NOX::Solver::Generic.
