Symmetric finite volume element method in ICF simulation

A symmetric finite volume element method (SFVEM) was established for two-dimensional three temperature radiation thermal conduction equations which are used to describe the process of heat conduction in laser-driven inertial confinement fusion (ICF), and the linear system of the equations with SFVEM was proved to be symmetrical. The new approach can improve the discretezation speed and energy conservation error comparing with standard finite volume element method (FVEM) and finite element method (FEM). Numerical examples confirm the conclusions.
