A multigrid solver for phase field simulation of microstructure evolution

Vanherpe, Liesbeth; Wendler, Frank; Nestler, Britta; … - In: Mathematics and Computers in Simulation (MATCOM) 80 (2010) 7, pp. 1438-1448

This paper presents a semi-implicit numerical method for the simulation of grain growth in two dimensions with a multi-phase field model. To avoid the strong stability condition of traditional explicit methods, a first-order, semi-implicit discretisation scheme is employed, which offers a good...

A two colorable fourth-order compact difference scheme and parallel iterative solution of the 3D convection diffusion equation

Zhang, Jun; Ge, Lixin; Kouatchou, Jules - In: Mathematics and Computers in Simulation (MATCOM) 54 (2000) 1, pp. 65-80

A new fourth-order compact difference scheme for the three-dimensional (3D) convection diffusion equation with variable coefficients is presented. The novelty of this new difference scheme is that it only requires 15 grid points and that it can be decoupled with two colors. The entire...
