I’m evaluating whether or not LAMMPS will work for a needed simulation. I’m wondering if LAMMPS can model granular particles in a moving fluid? The fluid undergoes a velocity due to a imposed pressure (aerosol jet). A certain amount of particles (parts-per-million) would be introduced into the fluid and accelerated. I’m unsure if this would involve code coupling or if LAMMPS has a “fix” command to apply a force/pressure to a fluid. Thanks!

wondering if LAMMPS can model granular particles in a moving fluid? The
from what you describe and my limited understanding of
the simulation of granular particles, it should be possible.
there are fix pour and fix addforce
please note that there is also the LIGGGHTS package that
is based on the LAMMPS code base, but has been enhanced
for granular simulations.
If all you want to really model is the particles, then LAMMPS
by itself can do it, which means the effect of the fluid
is implicit via commands like Axel mentioned (fix addforce, etc).
Those are very simple implicit effects. LAMMPS will compute
the particle-particle interactions accurately.
If you really want complex fluid behavior (hydrodynamics, etc)
and it sounds like you do, since you say a few parts-per-million
particles, then you need a real model of a fluid.
In that case, possibly the OpenFoam and LIGGGHTS work has
what you want.
