Cahn Hilliard Equation

Please login with a confirmed email address before reporting spam

Hi everyone!

Please, can someone help me? I have to do simulation on Comsol for Cahn-Hilliard equation, but the problem is that i'm trying since one week and nothing works.

The equation is: ?c / ?t=?.(M ?f) where f=A ?c+B c(1-c)(1-2c); A, B and M are constant.

Thanks in advance for your help.

Hi

it would be easier to read the formula from here :

en.wikipedia.org/wiki/Cahn-Hilliard_equation

Indeed a 4th order equation, must be split analytically first, try to introduce a variable

Good luck
