| Abstract: | The computational scheme and the basic idea of the Flux Corrected Transport (FCT) method are studied in the paper.With the numerical simulations of one dimensional stress waves,its applications to Finite Difference Method(FDM) and Finite Element Method (FEM) are also discussed.The results show that FCT method is very efficient in accurate describing the shock waves and eliminating the dispersive fluctuation behind the shock front. |
