Solve set of nonlinear equations

[christoph-maurer]

@vidanovic In a current research project, we work on interior roller blinds and exhaust air which is removed between the glazing and the roller blind. To calculate the air flow through the textile, we need to implement a pneumatic network. To calculate the resulting temperatures, we need to implement a thermal network with nodes at several heights. The networks lead to a set of nonlinear equations. Do you recommend NonLinearSolver.cpp as solver for such a task? Or should we add another solver like http://ceres-solver.org/ ? Thanks a lot for your advice!

@christoph-maurer Current solver is already dealing with non-linear equations. I would recommend you to try first with what is in the code and then if it does not work, to try new solver. However, keep in mind that solver is using simple replacement method with relaxation parameter and will try to change relaxation parameter if previous one fails. Since I do not know which equations you are trying to solve, maybe this will not work in your case and the solver is indeed necessary.
The above solver looks very interesting and I would like to try it for some other projects as well.
We could also make a zoom meeting about this if you want.

Thank you @vidanovic !
