高精度有限体积法与间断有限元法的比较
Comparison of high-precision finite volume method and discontinuous Galerkin method
摘要
Abstract
The high-precision finite volume method (FVM)and discontinuous Galerkin method (DGM)were compared in different test cases through numerical examples.Results show that:with the same precision,the calculation error of DGM is obviously less than that of FVM;DGM's reconstruction process is comparatively simpler than FVM's,but its computational time is much longer since its freedom-degree of polynomial solution is higher under the condition of high order and it needs to calculate volume points.Decreasing the freedom-degree numbers of polynomial solution in the time evolution process is an essential method for high-precision calculation in the reality applications.关键词
