Gauss VanLeer Scheme (2. Order)

This scheme is a numerical scheme 2. order. Comparing the results of the standard Gauss Linear against the Gauss VanLeer scheme, it can be demonstrated that the Gauss VanLeer scheme is stable and produces always physical results. The quantities of the passive scalar are within the bounded limited [0:1]. This scheme is widely used for the fluid fraction quantity in multiphase solvers.
