Shu, C-W, "Essentially Non-Oscillatory and Weighted Essentially Non-Oscillatory Schemes for Hyperbolic Conservation Laws", NASA/CR-97-206253. The user can choose the advecting streamfunction, the initial tracer field to advect and several advection schemes among with a 5th order WENO (Shu, 2001). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Since the WENO scheme uses all the candidate stencils, a clever choice of weights [5] results in a WENO scheme which is of order 2r1 in smooth regions [8]. weno is a non-oscillatory schema therefore, it can be applicated especially for a stable calculation with "zero risk" of numerical oscillation.
