  In this paper, we present a detailed example of numerical study of flm
formation in the context of metal coating. Subsequently we simulate wiping of
the film by a planar jet. The simulations have been performed using Basilisk, a
grid-adapting, strongly optimized code. Mesh adaptation allows for arbitrary
precision in relevant regions such as the contact line or the liquid-air impact
zone, while coarse grid is applied elsewhere. This, as the results indicate, is
the only realistic approach for a numerical method to cover the wide range of
necessary scales from the predicted film thickness (tens of microns) to the
domain size (meters). The results suggest assumptions of laminar flow inside
the film are not justified for heavy coats (liquid zinc). As for the wiping,
our simulations supply a great amount of instantaneous results concerning
initial film atomization as well as film thickness.
