Codice 11/2014 Titolo An offline-online Riemann solver for one-dimensional systems of conservation laws Data 2014-02-28 Autore/i Taddei, T.; Quarteroni, A.; Salsa, S. Link Download full text Abstract In this paper we present a new technique based on two different phases, here called offline and online stages, for the solution of the Riemann problem for one-dimensional hyperbolic systems of conservation laws. After theoretically motivating our offline-online technique, we prove its effectiveness by means of two numerical examples.
