These codes require an ASCII input file called input.dat of the following form:
Lower Limit on x Upper Limit on x Final Time
Pressure for x<0 when t=0 Density for x<0 when t=0 Speed for x<0 when t=0
Pressure for x>0 when t=0 Density for x>0 when t=0 Speed for x>0 when t=0
These codes produce 8 ASCII output files:
density.out. Density vs. x
entropy.out. Entropy vs. x
mach.out. Mach number vs. x
massflux.out. Mass flux vs. x
pressure.out. Pressure vs. x
sound.out. Speed-of-sound vs. x
velocity.out. Velocity vs. x
waves.out. A description of the solution in terms of the three waves defined in the book (+,-,0).
