Di. Popov et al., FOURIER COLLOCATION AND FOURIER GALERKIN METHODS APPLIED TO THE PHASE-FIELD MODEL OF 2-DIMENSIONAL PHASE-TRANSITION PROBLEMS, Journal of physics. D, Applied physics (Print), 31(19), 1998, pp. 2603-2611
Fourier collocation and Fourier Galerkin methods were employed for num
erical solution of phase-transition problems in two dimensions using t
he phase-field model. These methods were chosen in order to be able to
describe naturally the temporal evolution of periodic structures. The
applications to a modified Stefan problem and interphase boundary mot
ion driven by mean curvature are discussed. These two particular probl
ems were chosen because their phase-field description has received muc
h attention both from mathematical and from computational points of vi
ew. These phase-transition problems were modelled in a two-dimensional
periodic cell with no boundary conditions applied explicitly to the g
overning equations. This procedure allows modelling of more complicate
d periodic structures than those described here.
