  A method of simulating the drying process of a soft matter solution with an
implicit solvent model by moving the liquid-vapor interface is applied to
various solution films and droplets. For a solution of a polymer and
nanoparticles, we observe "polymer-on-top" stratification, similar to that
found previously with an explicit solvent model. Furthermore, "polymer-on-top"
is found even when the nanoparticle size is smaller than the radius of gyration
of the polymer chains. For a suspension droplet of a bidisperse mixture of
nanoparticles, we show that core-shell clusters of nanoparticles can be
obtained via the "small-on-outside" stratification mechanism at fast
evaporation rates. "Large-on-outside" stratification and uniform particle
distribution are also observed when the evaporation rate is reduced. Polymeric
particles with various morphologies, including Janus spheres, core-shell
particles, and patchy particles, are produced from drying droplets of polymer
solutions by combining fast evaporation with a controlled interaction between
the polymers and the liquid-vapor interface. Our results validate the
applicability of the moving interface method to a wide range of drying systems.
The limitations of the method are pointed out and cautions are provided to
potential practitioners on cases where the method might fail.
