Several types of meshless models for surfactant membranes,
which are particle-based solvent-free methods (i.e. topologically
unconstrained), have recently been developed and applied for
phenomena including membrane rupture, self-assembly, buckling,
and other types of structure formation. We extend one of them into
an explicit-solvent model to study structure formation dynamics
where hydrodynamics of the solvent matter. Especially, we
deal with dynamics of multi-lamellar structures under shear.
We find the membranes exhibit buckling instabilities with
appropriately high shear rate and membrane volume fraction.
In addition to the model descriptions and the simulation results,
the scheme of parallelized molecular dynamics, which is employed
in our study in conjunction with DPD-type thermostats, will also be
mentioned a bit in detail.
