You need the second term in the definition of $g$ because the first one alone, which is second order as well, yields an unstable scheme. (W)ENO, MUSCL,... all have some more tricks to handle discontinuities like flux limiters. I wanted to know if there are plain third or fourth order schemes like Lax-Wendroff. Gibbs will be there, of course, but it should be stable. $g(v_0,\dots,v_3) = \frac{7}{12}(f(v_1)+f(v_2)) - \frac{1}{12}(f(v_0) + f(v_3))$ yields a fourth order scheme, but it's not stable. | |
