摘要
阐述了通量修正输运法（ＦＣＴ方法）的计算格式及其原理。并以一维应力波为例，讨论了ＦＣＴ方法在有限差分与有限元中的应用。结果表明ＦＣＴ方法对于提高冲击波分辨率和消除波后振荡是有效的。
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.
