Nonlinear parabolic PDE with PDE toolbox

Hi,

I'd like to solve the PDE

$\partial u / \partial t = r*(\partial/\partial r[r*D0*(u/u0)^n])$
 where D0, C0 and n are constants and $u=u(r,t)$

using the PDE toolbox. However, I don't seem to be able to find a way to set it up - mainly finding the coefficients to specify the PDE. Is there a way to do it? Any help would be much appreciated.

Thanks!

Generally, PDE Toolbox solves problems with second-order spatial derivatives. If you can manage to convert your problem into this form, then you can specify coefficients as documented.

Good luck,
