NonlinearSolver

Options for the non-linear solver.

Fields

nonlinear_solver_type: NonlinearSolverType, default = Undefined

Method for the non-linear solver.
relative_tolerance: Float, default = 1e-8

Relative convergence tolerance. Default is 1e-8.
absolute_tolerance: Float, default = 1e-8

Absolute convergence tolerance. Default is 1e-8.
relative_change_tolerance: Float, default = 1e-8

Convergence tolerance in terms of the norm of the change in the solution between steps. Default is 1e-8.
relative_change_residual_norm_tolerance: Float, default = 1e8

Convergence tolerance in terms of the change of the residual norm between the current and first iterations. Default is 1e8.
maximum_iterations: Integer, default = 25

Maximum number of iterations. Default is 25.
extrapolation_type: ExtrapolationType, default = Undefined

Type of extrapolation for the initial guess of the Newton-Raphson solver. Default is linear extrapolation.
