Hello everyone, I would like to use pdepe for solving a heat equation 1D space, so it looks good. But I don't really understand where the diffusion coefficient is ?
I would like to solve : (1)--> du/dt = d/dx(D(u) du/dx) with D(u) the non linear diffusion coefficient function of u. Is it possible to put D(u) at this location in the equation (1)?
Thanks to the community. :)
