Cahn-Hilliard Equation

The Cahn-Hilliard equation describes the evolution of a conserved concentration field during phase separation. The gradient is obtained from equations 11 or 10. For the isotropic case gradient flow in the tex2html_wrap_inline1064 norm with a constant mobility tex2html_wrap_inline1326 gives the isotropic Cahn-Hilliard equationgif:

  equation729

With anisotropic interfaces and a isotropic composition dependent tex2html_wrap_inline1326 this equation would be

  equation731
