continuation_option2rheolef

Overview

This class is used to send options to the continuation function (see continuation(4)).

Flags

tol

max_iter

These options are transmitted to the damped_newton algorithm called during the continuation algorithm.

ini_delta_parameter

max_delta_parameter

max_delta_parameter

These options control the continuation parameter evolution along the branch of solution. When using the Keller continuation, these options control the arc-length parameter.

n_adapt

When non-zero allows one to activate the optional mesh adaptation feature (see adapt(4)) embedded in the continuation algorithm.
