摘要: When approximating a hyperbolic system of conservation laws w t + {f(w)} = 0 with so-called upwind differences, we must, in the first place, establish which way wind blows. More precisely, must determine direction each variety signals moves through computational grid. For this purpose, physical model interaction between cells is needed; at present two such models are use.
