Finite Volume Method Numerical ux For a hyperbolic problem, information propagates at a nite speed. So it is reasonable to assume that we can obtain Fn i 1=2 using only the values Qn i 1 and Q n i: Fn i 1=2 = F(Q n 1;Q n) where Fis some numerical ux function.

Numerical flux functions based on an exact or approximate solution of the Riemann problem of gas dynamics are discussed. IntroductionIn this paper, we are interested in the finite volume element method (FVEM) for the following second order linear hyperbolic initial boundary value problem: Given f (x, t), g(x) and w(x), and t ∈ (0, T ] for x ∈ Ω, find u = u(x, t) such that u tt − ∇.(A(x)∇u) = f (x, t) ∀x ∈ Ω, 0.
