Classical interatomic potentials provide a means of linking atomic interactions to larger scale dynamic materials properties. A primary challenge with these investigations is that the predicted results are often extremely sensitive to the choice of interatomic potential. This research will focus on performing high throughput calculations to explore dynamic property predictions across interatomic potentials, temperatures, and atomic configurations. An understanding of statistical analysis is important for processing the time series results of individual calculations as well as comparing multiple calculations. Experience with coding, web design and database interactions will help as all source code, calculation methods, and results will be made openly available as described below.
Processed results will be presented on the NIST Interatomic Potentials Repository, with raw data accessible from a CDCS database hosted at https://potentials.nist.gov/.
Calculation methods will be integrated into the iprPy calculation framework , with source code available on github.
