“…In recent years, another interesting ABC for finite volume (FV) schemes was discovered empirically, e.g., Leveque [6] and Loh et al [7][8][9][10]. When the flow conditions prescribed at the ghost cell centers (GCCs) do not match the flow within the domain, a matched layer similar to the one in the PML method is automatically captured at the boundary to do the matching, saving the work of creating a matched layer or matching the flow data.…”

a b s t r a c tIn this paper, a new definition of SE and CE, which is based on the hexahedron mesh and simpler than Chang's original CE/SE method (the space-time Conservation Element and Solution Element method), is proposed and an improved CE/SE scheme is constructed. Furthermore, the improved CE/SE scheme is extended in order to solve the elastic-plastic flow problems. The hybrid particle level set method is used for tracing the interfaces of materials. Proper boundary conditions are presented in interface tracking. Two high-velocity impact problems are simulated numerically and the computational results are carefully compared with the experimental data, as well as the results from other literature and LS-DYNA software. The comparisons show that the computational scheme developed currently is clear in physical concept, easy to be implemented and high accurate and efficient for the problems considered.

SUMMARYA new numerical scheme, namely space-time conservation element and solution element (CE/SE) method, has been used for the solution of the two-dimensional (2D) dam-break problem. Distinguishing from the well-established traditional numerical methods (such as characteristics, finite difference, finite element, and finite-volume methods), the CE/SE scheme has many non-traditional features in both concept and methodology: space and time are treated in a unified way, which is the most important characteristic for the CE/SE method; the CEs and SEs are introduced, both local and global flux conservations in space and time rather than space only are enforced; an explicit scheme with a stagger grid is adopted. Furthermore, this scheme is robust and easy to implement. In this paper, an improved CE/SE scheme is extended to solve the 2D shallow water equations with the source terms, which usually plays a critical role in dam-break flows. To demonstrate the accuracy, robustness and efficiency of the improved CE/SE method, both 1D and 2D dam-break problems are simulated numerically, and the results are consistent with either the analytical solutions or experimental results.
