1D Euler equations - Interacting Blast Waves

Problem description       Results:   5 Levels

This difficult test case of two interaction blast waves has been designed especially to illustrate the strong relationship between the accuracy of the overall flow solution and the sharp resolution of discontinuities.

Initial / Boundary Conditions

rho=1.0  u=0.0  p=1000.0    for 0.0 < x < 0.1
rho=1.0  u=0.0  p=0.01    for 0.1 < x < 0.9
rho=1.0  u=0.0  p=100.0    for 0.9 < x < 1.0

Reflecting boundary conditions at both sides.
