The Cahn-Hilliard model describes the phase separation process in a binary mixture, such as oil and water.
The system's evolution in terms of concentrations obeys the following partial differential equation:
$$
\frac{\partial c}{\partial t} = D \nabla^2 (c^3-c-\gamma\nabla^2 c)
$$
where $c\in[-1,1]$ is the concentration of fluid, -1 means highest concentration of species $A$,
1 means highest concentration of species $B$.
Parameters: $D$ is a diffusion coefficient and $\gamma$ characterizes the sharpness of transition regions.
Periodic boundary conditions are applied to the simulation domain.

The behavior of this model shows similarity to the Ising model where neighboring cells influence each other on a 2 state grid space, however, here, the value on each point of the grid has values in $[-1,1]$.
