We
present a mesoscopic model for simulating the
dynamics of a non-volatile liquid on a solid substrate. The wetting properties
of the liquid can be tuned from complete wetting to total non wetting. The
velocity boundary condition at the solid interface can be controlled so that
either perfect stick or slip can be induced. This model opens thus the way to
study the dynamics of drops and liquid thin films at mesoscopic
lengths scales. As applications, we study the role of thermal fluctuations on
the spreading of nanodroplets and the effect of slip
on the morphology of dewetting thin films.
