v7 v8 7 7 As you can see, the 1st order monotone schemes are more 'diffusive' than the higher order schemes, i.e. they clip extreme values of the solution. By the 1250 time steps, this effect is highly exaggerated: 8 8 9 [[Image(compare2.png ]]9 [[Image(compare2.png)]] 10 10 11 11 The higher order schemes as you can see here are 'dispersive'. That is, they suffer from slight sign errors in the position of the wave, with the numerical solution either lagging behind or ahead of the true solution.
