A pragmatical analysis of discretization procedures for initial and boundary value problems in gas dynamics and their influence on accuracy or look Ma, no wiggles
Gino Moretti · NASA STI/Recon Technical Report N · 1974
Abstract : Examples are given of gas dynamical problems treated numerically, where apparently minor changes to the coding eliminate all numerical oscillations and instabilities. In each case, the changes are justified by physical considerations and the importance of consistency of coding with physical properties is emphasized.
