N2 - One of the fundamental signatures of the Quark Gluon Plasma has been the suppression of heavy flavor (specifically D mesons), which has been measured via the nuclear modification factor, RAA and azimuthal anisotropies, vn, in large systems. However, multiple competing models can reproduce the same data for RAA to vn . In this talk we break down the competing effects that conspire together to successfully reproduce RAA and vn in experimental data using Trento+v-USPhydro+DAB-MOD. Then using our best fit model we make predictions for RAA and vn across system size for 208PbPb, 129XeXe, 40ArAr, and 16OO collisions. We find that 0-10% centrality has a non-trivial interplay between the system size and eccentricities such that system size effects are masked in v2 whereas in 30-50% centrality the eccentricities are approximately constant across system size and, therefore, is a better centrality class to study D meson dynamics across system size.
