The Sod shock tube problem, named after Gary A. Sod, is a common test for the accuracy of computational fluid codes, like Riemann solvers, and was heavily investigated by Sod in 1978.The test consists of a one-dimensional Riemann problem with the following parameters, for left and right states of an ideal gas. , where * is the density * is the pressure * is the velocity The time evolution of this problem can be described by solving the Euler equations,which leads to three characteristics, describing the propagation speed of thevarious regions of the system. Namely the rarefaction wave, the contact discontinuity andthe shock discontinuity.If this is solved numerically, one can test against the analytical solution,and get information how well a code captures and resolves shocks and contact discontinuitiesand reproduce the correct density profile of the rarefaction wave.

DDPS | Model reduction of partial differential equations via optimization-based feature tracking
In this DDPS talk from June 24, 2021, University of Notre Dame assistant professor Matthew Zahr introduces an optimization-based model reduction framework to solve conservation laws with parametrized, discontinuous solution features such as shock waves. The proposed reduction framework s

Accidents were common in the early age of submarines. If something went wrong, there was little technology available to rescue trapped submariners. Naval officer Charles Momsen designed new equipment to save submariners from a ghastly fate. In May 1939, his invention was put to the test.
