Rough surface stratified

The simulations here are of the surface of a solid which has been fractured under stress (parameter estimates for alpha, C1, H from Schmittbuhl and Schmitt 1996).

Sphero-scale increasing from 1/16 (upper left) to 128 (lower right). The parameters are a=1.5, C1=0.3, H=0.8, d=1,c=-0.4, e=0.25 ,ls=2^i with i=-4 to 7
