Abstract
A new numerical method is proposed for multidimensional linear advection equations. The scheme uses a cubic spatial profile within grids, and is described in an explicit form by assuming that both a physical quantity and its spatial derivative obey the given equation. The method gives a stable and less diffusive result without any flux limiter. Its extension to nonlinear equations with nonadvection term is straightforward.
