When CFL=1, it should give exact solution. But, it's amplitude is damped and its charactristic lines changed their directions,by the way the initial condition is sin(pi(x)) when x is between 0 and 2 and 1 when x is between 2 and 5. Do I miss any step? How can I get the exact solution I've expected? Thanks in advance geometry dash scratch Last edited by davidacker; March 4, 2024 at 19:04.
