  The wetting dynamics of liquid particles, from coated droplets to soft
capsules, holds significant technological interest. Motivated by the need to
simulate liquid metal droplet with an oxidize surface layer, in this work we
introduce a computational scheme that allows to simulate droplet dynamics with
general surface properties and model different levels of interface stiffness,
describing also cases that are intermediate between pure droplets and capsules.
Our approach is based on a combination of the immersed boundary (IB) and the
lattice Boltzmann (LB) methods. Here, we validate our approach against the
theoretical predictions in the context of shear flow and static wetting
properties and we show its effectiveness in accessing the wetting dynamics,
exploring the ability of the scheme to address a broad phenomenology.
