Zusammenfassung:
We present numerical studies of wetting on various topographic substrates, including random topographies. We
find good agreement with recent predictions based on an analytical interface-displacement-type theory, except
that we find critical end points within the physical parameter range. As predicted, Gaussian random surfaces
are found to behave qualitatively different from non-Gaussian topographies. This shows that Gaussian random
processes as models for rough surfaces must be used with great care, if at all, in the context of wetting phenomena.
