A grid refinement study is performed for mean-field plasma boundary simulations with fluid neutrals in an EU-DEMO geometry. In general, grid convergence of the simulations is achieved, with differences between the finest and second-finest grid of \<5\% for the majority of the quantities of interest. The estimated discretization errors for the original 96 x 36 grid are mostly in the 4\%-25\% range. However, it is also shown that exceptions are possible due to the non-linear nature of plasma boundary codes. Hence, it is advised to regularly perform grid refinement studies on subsets of cases.
