LAMMPS received an R&D 100 award in 2018. These awards are given annually -- see their website. They are an industry-wide competition rewarding the practical applications of science.
The award summary was as follows:
LAMMPS: Atomistic Simulation of Materials
LAMMPS is a widely-used molecular dynamics simulation package that models materials from the atomistic to mesoscale to continuum scales. It can be run on machines from desktop computers to the largest supercomputers, to explore the structural and dynamic properties of materials and provide insights not easily accessible to experimental observation.
Here is a brief video which was part of the submission.
