Sandia Open-Source Simulator Helps Solve the Mysteries of Metal Hardening

HPC materials simulations at LLNL are revealing surprising insights into how metals behave under extreme pressure. Check out this research highlight on metal hardening from Science & Technology Review. Using Vulcan and Sequoia, two of our most powerful computers, a research team leveraged the LAMMPS (Large-Scale Atomic/Molecular Massively Parallel Simulator) molecular dynamics simulator to run simulations of a corrosion-resistant metal called tantalum. Developed by our colleagues at Sandia National Laboratories, LAMMPS is an open-source code that allows users to study the physical movement of atoms and molecules.
