Query: Mesoscopic modelling of droplets on topologically patterned substrates   We present a lattice Boltzmann model to describe the spreading of droplets on
topologically patterned substrates. We apply it to model superhydrophobic
behaviour on surfaces covered by an array of micron-scale posts. We find that
the patterning results in a substantial increase in contact angle, from $110^o$
to $156^o$.
