Numerical studies of the Cahn-Hilliard equation for phase separation. (English) Zbl 0632.65113
The behaviour of the solution of the initial-boundary value problem $$U_ t+\gamma D^ 4U=D^ 2\Phi (u),\Phi (u)=\gamma_ 2u^ 3+\gamma_ 1u^ 2+\gamma_ 0u,$$ $$D=\partial /\partial x$$, $$\gamma,\gamma_ i$$ are constants, $$Du=\gamma D^ 3u-D\Phi (u)$$ $$(x=0$$, $$x=L)$$ $$u(x,0)=u_ 0(x)$$ is studied using a finite element Galerkin method. Also, numerical experiments are discussed.
