Synopsis
NoNonlinearSolver()
Description
NoNonlinearSolver is the trivial NonlinearSolverBase. When selecting a
solver in AdvancedSolverMode, specifying
NoNonlinearSolver as the
nonlinear_solver parameter will cause OOF2 to
assume that the SubProblem is linear.
Selecting NoNonlinearSolver for a nonlinear
SubProblem will lead to unpredictable results. An explicit time stepper, such as
ForwardEuler or RK4 will still work, but other steppers
will be unreliable. Static solutions will be incorrect.
In BasicSolverMode,
NoNonlinearSolver is used automatically for
linear problems.
