【Abstract】 In this paper,multistep differences method and characteristic finite element method method are coupled,then the flat non-homogeneous current and silt sedimentation model is simulated by the multistep differences-characteristic finite element method,and corresponding error estimates are derived.At last,numerical experiments are presented to justify the theoretical analysis.更多还原
