LAMMPS USER-CGSDK example problems
Each of these sub-directories contains a sample problem for the SDK
coarse grained MD potentials that you can run with LAMMPS.
These are the two sample systems
peg-verlet: coarse grained PEG surfactant/water mixture lamella
verlet version
this example uses the plain LJ term only, no charges.
two variants are provided regular harmonic angles and
the SDK variant that includes 1-3 LJ repulsion.
sds-monolayer: coarse grained SDS surfactant monolayers at water/vapor
interface.
this example uses the SDK LJ term with coulomb and shows
how to use the combined coulomb style vs. hybrid/overlay
with possible optimizations due to the small number of
charged particles in this system
