摘要：Time-dependent partial differential equations (PDEs) are widely used for contamination flows and electromagnetic wave propagations. Due to the computational complexity and the large scale and long term prediction, it is important to develop efficient conservative numerical methods for solving time-dependent PDE problems. In this talk, we would like to present our development of conservative methods and their parallel algorithms for the problems. Meanwhile, we will also present our study of conservative local refinement to electromagnetic propagations. Numerical experiments demonstrate the performance of the developed methods.
