Hi.(adsbygoogle = window.adsbygoogle || []).push({});

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) and/or a reputable book dedicated towards von Neumann (or Fourier) stability analysis?

Thank you for your time,

Will
