AB - <p style="text-align: justify;">We study the static and dynamical behavior of the contact line between two
fluids and a solid plate by means of the Lattice Boltzmann method (LBM). The different fluid phases and their contact with the plate are simulated by means of standard
Shan-Chen models. We investigate different regimes and compare the multicomponent vs. the multiphase LBM models near the contact line. A static interface profile
is attained with the multiphase model just by balancing the hydrostatic pressure (due
to gravity) with a pressure jump at the bottom. In order to study the same problem
with the multicomponent case we propose and validate an idea of a body force acting
only on one of the two fluid components. In order to reproduce results matching an
infinite bath, boundary conditions at the bath side play a key role. We quantitatively
compare open and wall boundary conditions and study their influence on the shape of
the meniscus against static and lubrication theory solution.</p>
