Variable coefficient?

[JohanCar1sson]

I didn't see an example with variable coefficients. Can I use py-pde to solve this?
df/dt = d/dx (1-x*x) df/dx

I'm not quite sure what you mean by "variable coefficients", but the package certainly supports non-linear PDEs, which is demonstrated by most examples.

Thanks for the quick response, and for providing py-pde! Yes, I did figure it out. There is a nice example ("Diffusion equation with spatial dependence"), but I ended up deriving a class from PDEBase that I can later generalize to do what I need. The toy problem above I did manage to solve already.
