Hyperbolic equations: domain of dependence

  1. Jun 21, 2011 #1
    In many cfd textbooks the domain of dependence is stated as the entire region emclosed by the characteristics. Is this correct? Isnt it only the values on the characteristics?

    It is correct as you can get from any point in the region enclosed by the characteristics to any other point within the region enclosed by the characteristics.

    Think of it like a light-cone if that helps.
