I am interested in trying to use newton iterations, rather than simply fixed-point iterations, to speed up the convergence of the non-linear iterations in my fipy problem.
I have found this mention of a term useful for newton iterations, http://www.ctcms.nist.gov/fipy/fipy/generated/fipy.terms.html#module-fipy.terms.residualTerm and I see this mention of an example using newton iterations https://github.com/usnistgov/fipy/wiki/ScharfetterGummel but I don't see the actual code it is talking about. Is there an example available somewhere? Kris
