FD1D_BURGERS_LEAP is a FORTRAN77 program which solves the nonviscous time-dependent Burgers equation using finite differences and the leapfrog method.
The function u(x,t) is to be solved for in the equation:
du/dt + u * du/dx = 0for a <= x <= b and t_init <= t <= t_last.
Problem data includes an initial condition for u(x,t_init), and the boundary value functions u(a,t) and u(b,t).
The non-viscous Burgers equation can develop shock waves or discontinuities.
