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 adaptive mesh refinement technique is presented in numeri-cal solution of partial differential equations. Mainly including scanning function,refining/ derefine, and the method has been implemented based on unstructuregrid and in Lagrangian or in Eulerian. Results are very helpful to the study of thenumerical simulation of detonation and study of explosive performances.
