- 1D linear convection (Lecture 2: 25:42)

The ultimate simplification. Removed non-linearity. C transport velocity.
u is anything.
Initial profile u(x,t = 0) = u0(x)
After time t, u(x) is just the initial profile displased with distance x = ct
δu / δt + cδu / δx = 0
Solution: u(x,t) = u0(x - xt)
Wave propagation, and that means pure convection!
Space time discretization
i -> indec of grid in x n -> index of grid in t
Numerical scheme
