介绍了通量校正输运（FCT）格式向非结构网格的扩展。通过有限元进行空间离散化。特别是，在两个维度的三角形元素已被选中。极限过程是基于Zalesak（1979）对Boris和Book（1973）发展的FCT格式的多维扩展。由此产生的计划，FEM-FCT，是能够解决移动和固定的冲击在两个元素，并给出了几个例子，证明达到的精度，即使是复杂的几何形状。
The extension of flux-corrected transport (FCT) schemes to unstructured grids is presented. The spatial discretization is performed via finite elements. In particular, triangular elements in two dimensions have been chosen. The limiting procedure is based on Zalesak's (1979) extension to more than one dimension of the FCT schemes developed by Boris and Book (1973). The resulting scheme, FEM-FCT, is capable of resolving moving and stationary shocks within two elements, and several examples are given that demonstrate the accuracy attainable, even for complicated geometries.
