1. Unlike Step-7, I have Neumann-only BCs. In my prior experience with
the FD and FV methods, this is a difficult problem. Is there any
specific advice that can help me with this?
But step-7 also has Neumann boundary conditions. What is different in
your case? That you *only* have Neumann
Hi Daniel,
Thank you for your reply. I had seen all the tutorials you mentioned.
Let me further clarify some of the things in my PDE that are somewhat
different from the tutorials.

Krishna,
Have a look at step-7 for Neumann boundary conditions, step-15 for
nonlinear problems and step-26 for time-dependent problems to get started.
Let us know if you have more specific questions.
Best,
Daniel

I need to solve the following non-linear diffusion equation on a unit 1D
domain:
du/dt = \nabla \dot ( D(u) \grad u)
subject to Neumann bcs at both ends. D(u)*grad(u) = f(t) at x=0, and
D(u)*grad(u) = 0 at x=1, with a constant initial condition u(x,0) = u0
The difficulty with this problem is
