  A systematic study for a single-specie lattice Boltzmann model with
frustrated-short range attractive and mid/long-range repulsive-interactions is
presented. The equilibrium analysis is performed along the guidelines proposed
by [X. Shan, Phys. Rev. E 77, 066702 (2008)] and allows us to determine the
surface tension density and the resulting disjoining pressure developing in a
thin film when two interfaces overlap. Numerical simulations of confined flows
are then performed with a multicomponent model and are successfully tested
against the recent suggestion by Bocquet and coworkers on the existence of a
cooperative length underlying the non-local rheology of highly confined
soft-glassy materials [Goyon et al., Nature 454, 84-87 (2008); Soft Matter 6,
2668-2678 (2010)].
