.SH NAME
continuation_option \- continuation solver options (rheolef-7\&.1)
.PP
.SH "DESCRIPTION"
.PP
This class is used to send options to the \fBcontinuation(3)\fP algorithm\&.
.SH "OPTIONS"
.PP
\fCtol\fP 
.br
\fCmax_iter\fP 
.PP
.RS 4
These options are transmitted to the \fBdamped_newton(3)\fP algorithm during the \fBcontinuation(3)\fP algorithm\&. 
.RE
.PP
\fCini_delta_parameter\fP 
.br
\fCmax_delta_parameter\fP 
.br
\fCmax_delta_parameter\fP 
.PP
.RS 4
These options control the \fBcontinuation(3)\fP evolution along the branch of solution\&. When using the Keller continuation, these options control the arc-length parameter\&. 
.RE
.PP
\fCn_adapt\fP 
.PP
.RS 4
When non-zero, it allows one to activate the optional mesh adaptation feature (see \fBadapt(3)\fP) embedded in the continuation algorithm\&. 
.RE
.PP
.SH "TODO"
.PP
Complete the documentation of all the others options\&.
.SH "IMPLEMENTATION"
.PP
This documentation has been generated from file main/lib/continuation_option\&.h
.PP
The \fC\fBcontinuation_option\fP\fP class is simply derivated from the \fCadapt_option\fP one (see \fBadapt(3)\fP):
