Following nonlinear solvers are available in OpenGeoSys:
The nonlinear solver of “Newton” type is an implementation of the NewtonRaphson method. The basic definition of the nonlinear solver with “Newton” follows this template:
<nonlinear_solver>
<name>basic_newton</name>
<type>Newton</type>
<max_iter>10</max_iter>
<linear_solver>linear_solver</linear_solver>
</nonlinear_solver>
The nonlinear solver of “Picard” type is an implementation of the PicardIteration method. The basic definition of the nonlinear solver with “Picard” follows this template:
<nonlinear_solver>
<name>basic_picard</name>
<type>Picard</type>
<max_iter>100</max_iter>
<linear_solver>linear_solver</linear_solver>
</nonlinear_solver>
