  The Lattice Boltzmann method has been gaining acceptance for hydrodynamic
problems involving complex boundaries, non-equilibrium dynamics and interfacial
phenomena in multiphase or multicomponent systems. lb2d.pm is a Perl module
offering a clear framework for simple Lattice Boltzmann simulations in 2D. The
syntax and some basic applications are presented. Mainly, the new version 0.1
enables solute transport and accounts for reactive boundaries leading to
surface growth.
