Abstract
After having recalled the basic concepts of residual distribution (RD) schemes, we provide a systematic construction
of distribution schemes able to handle general unstructured meshes, extending the work of Sidilkover. Then, by using
the concept of simple waves, we show how to generalize this technique to symmetrizable linear systems. A stability
analysis is provided. We formally extend this construction to the Euler equations. Several test cases are presented to
validate our approach.

1. Introduction
The numerical simulation of compressible flows is generally done via some generalization of the one-
dimensional Lax­Wendroff scheme. It is well known that this scheme is stable in the energy norm, but does
not have any stability property in the maximum norm. The simulation of flows with strong discontinuities
can only be performed with schemes having properties in the maximum norm, because we want solutions
