  The lattice Boltzmann method has become a standard technique for simulating a
wide range of fluid flows. However, the intrinsic coupling of momentum and
space discretization restricts the traditional lattice Boltzmann method to
regular lattices. Alternative off-lattice Boltzmann schemes exist for both
single- and multiphase flows that decouple the velocity discretization from the
underlying spatial grid. The current study extends the applicability of these
off-lattice methods by introducing a finite element formulation that enables
simulating contact line dynamics for partially wetting fluids. This work
exemplifies the implementation of the scheme and furthermore presents benchmark
experiments that show the scheme reduces spurious currents at the liquid-vapor
interface by two orders of magnitude compared to a nodal implementation and
allows for predicting the equilibrium states accurately in the range of
moderate contact angles.
