Hi AlephZero. Thank you for the reply. No, I'm not referring to numerical experiments. I'm referring to the theoretical CFL condition and to a very basic application of von Neumann stability analysis where u^m_n = (g^m)(exp(i*xi_n*h)) and the scheme is u^(m+1)_n = u^(m-1)_n +...

Hi. I'm trying to determine the CFL condition for the fourth-order leapfrog scheme. I'm finding 2 as what's published, which does not match what I'm getting. Does anyone know where I can find a von Neumann (or Fourier) stability analysis of the leapfrog (2,4) scheme (so I can compare my work)...
