## Multidimensional upwinding. I: The method of transport for solving the Euler equations.(English)Zbl 0932.76050

Summary: We present a new discretization of muldidimensional conservation laws. The idea of transport associated with the solution of a scalar equation is used for the convective part of the compressible Euler equations. Then we derive a multidimensional wave structure to model the acoustic part of this nonlinear system, that allows infinitely many propagation directions in the numerical method. This provides the basic knowledge to construct a numerical method that does not rely on Riemann solvers. A more general definition of the waves, together with the concept of consistency, enables the design of effective multidimensional methods. $$\copyright$$ Academic Press.
