landlab.components.advection.flux_limiters¶

Flux limiter functions for advection solver.

There are many flux-limiter functions. For second-order TVD schemes, there is an envelope of acceptable values of phi(r):

r <= phi(r) <= 2r, (0 <= r <= 1)
phi(1) = 1
1 <= phi(r) <= r, (1 <= r <= 2)
1 <= phi(r) <= 2, (r > 2)
