The purpose of this example is to demonstrate how to combine different molecules using radically different pair pair styles together in the same simulation (using moltemplate).
This is an example of a single all-atom methanol molecule immersed in coarse grained ELBA water. In this example, the initial positions of the molecules were randomly generated by PACKMOL. Since PACKMOL does not know anything about dipoles, initially all of the dipoles are pointing in the +x direction, but they will point in random directions after reaching equilibrium during a short LAMMPS simulation at room temperature.
This example was provided by Oscar Matus Rivas at McGill University.
More detailed instructions on how to build LAMMPS input files and run a short simulation are provided in other README files.
This file explains how to use moltemplate.sh to build the files that LAMMPS needs.
This file explains how to use LAMMPS to run a simulation using the files you created in step 1.
This example requires that LAMMPS was built with the "DIPOLE" package. If lammps complains of a missing pair style, you will have to recompile LAMMPS with the "DIPOLE" package enabled. For details see: https://lammps.sandia.gov/doc/Build_package.html
