The main modifications are:
AdvectTracerroutine into two separate methods. Method 0 corresponds to the already implemented velocity field interpolation method. Method 1 is the new flux-based method. The method can be specified in the input file within the<tracer>section, using themethodparameter.A comparison of the two methods is presented below, and can be compared to Fig. 9 from https://ui.adsabs.harvard.edu/abs/2013MNRAS.435.1426G/abstract.

A 2D test using the Kelvin-Helmholtz and method 1 is also presented below.
