A method is presented for tracking interfaces, which is MOCL (marker on cell line) employed in two-dimensional Eulerian code. To test it, five kinds of objects with different shapes being uniform motion are numerically simulated in a two- dimensional Eulerian hydrodynamics code that uses the MOCL technique to track interfaces. Results show that the method is simple and feasible.

In this paper, an overlapping domain decomposition method for solvingthe exterior boundary value problem of plane elasticity equation by using naturalboundary reduction is discussed. This method is effective especially for problems overunbounded domains. The geometric convergency is proved. The theoretical results aswell as the numerical examples show that the convergence rate of this discreteSchwarz iteration is independent of the finite element mesh size, but dependent onthe frequency of the exact solution and the overlapping degree of subdomains.
In this paper, we develop the cascadic multigrid method for parabolic problems. The optimal convergence accuracy and computation complexity are obtained.
