'wired' as strange. it has to many bumps. should be less compicated in places where D is changing

I am trying to use a explicit FDM for transient 1d conditions with linear elements for specific diffusion equation: ds/dt=D(x)*d2s/dx2+R(s) the problem is that I am using different, nonlinear functions describing diffusion constant D(x) and reaction rate R(s). The diffusion parameter is...
