摘要 随着界面追踪方法的发展,各种高分辨率、高精度的差分格式得到了广泛的应用。在实际计算中,有时人们只追求差分格式的形式,采用流行的差分格式,忽略了高阶传统型差分格式不仅构造简单,而且具有良好的分辨率。用5阶迎风偏斜格式、积分平均型TVD格式和5阶WENO格式求解Level Set方程,通过求解典型的界面追踪数值算例,发现用5阶迎风偏斜差分格式求解Level Set方程不仅构造简单而且计算结果具有很高的精度。 Along with the development of method for tracing interface, high order and high resolution scheme were used widely. In actual computation, people pay attention to the scheme shape, and use the popular scheme sometimes, and ignore the high order traditional scheme which has simple structure and high resolution. In this paper, the Level Set equation is solved with 5th order upwind deflective scheme, TVD integrate average method and 5th WENO scheme, and by solving the classical examples of tracing interface, the author found that solving Level Set equation with 5th order upwind deflective scheme has simple structure and highly accurate results.
