摘要
本文结合有限体积方法和有限元方法处理非线性对流扩散问题 ,非线性对流项利用有限体积方法处理 ,扩散项利用有限元方法离散 ,并给出近似解的误差估计 .
In this paper, we combined finite element method and finite volume method to deal with nonliear convection diffusion problems. The nonlinear advective term is approximated by finite volume method and the diffusive term is discretized by finite element method. The error estimates are given in the end.
