摘要:For the numerical simulation of Lagrangian multi-material radiation hydrodynamic problems, a challenging problem is to construct discrete schemes to solve energy diffusion equations with discontinuous coefficients on Lagrangian distorted meshes. This talk will describe briefly the physical background and some key numerical issues related to cell-centered finite volume schemes. Then some finite volume schemes satisfying maximum principle for diffusion equations on general meshes are constructed with a new way. Moreover, some numerical results will be presented to show the performance of our schemes.
