AI Agent Automates Atomistic Simulations for Materials Design
Within the URSA (Universal Research and Scientific Agent) framework, researchers have created an agent-based system that automates atomistic simulations utilizing the LAMMPS tool. This system independently chooses interatomic potentials, designs and executes simulations, and incorporates iterative error recovery in a closed-loop process. Its scientific validity was evaluated against LAVA, a high-throughput toolkit for LAMMPS and VASP computations. By minimizing the need for manual input and reducing trial-and-error, the framework enhances the rigor, reproducibility, and scalability of atomistic modeling.
