WebAs indicated a(u) has to be approximated at the indices (j + 1 / 2) and (j − 1 / 2). This may simply be done by averaging the neighbouring values: aj + 1 / 2 = 1 2(un j + un j + 1) for the burger equation. Another method that assure conservation is to use the following approximation aj + 1 / 2 = {Fn j + 1 − Fn j un j + 1 − un j if uj + 1 ...
