Inline Newton iterations

[adtzlr]

In nonlinear viscoelasticity / plasticity it is sometimes required to numerically solve a dissipation / viscoelastic evolution ODE / PDE with the Newton-Rhapson method.

Tasks

• Outline whether it is possible to use casadi.rootfinder(label, "newton", casadi.Function).

• Is it useful to provide a wrapper-function which creates the function object of a given (equilibrium) equation to solve?

Optional

• Add a test.

• Add an example.
