Detailed Description

Abstract nonlinear solver method interface.

Defines the type of access methods into the iterative nonlinear solvers.

Instantiate or reset() the solver.
Find the solution via solve() or perform a single iterations via iterate().
Get information about the current solver state via getSolutionGroup(), getPreviousSolutionGroup(), getNumIterations(), and getParameterList() — particularily useful for NOX::StatusTest methods.
Get the current status of the solver via getStatus().

pure virtual

Reset the nonlinear solver for a new solve.

Parameters

tests	Status tests to check for convergence or failure. These tests will be modified by the solver.
params	List of parameters. These parameters will be modified by the solver.

Note: All the objects passed to reset() will be modified.; The group object will be cloned via NOX::Abstract::Group::clone(), and the vectors within will also be individually cloned via NOX::Abstract::Vector::clone().

Warning: If the contents of grp, tests, or params are modified by the calling program after calling reset(), then the behavior of iterate() and solve() are completely undefined. To remedy this, call reset() again with the modified objects.

Implemented in NOX::Multiphysics::Solver::FixedPointBased.
