Abstract Scope Although an extremely capable tool, one of the steadfast shortcomings of density functional theory based molecular dynamics (DFT-MD) simulations have been their computational costs. Because of the ability of these quantum mechanics based calculations to predict thermodynamic properties, there is great interest in a machine learning approach. We built a high-quality DFT-MD dataset for the body-centered cubic structure (bcc) of zirconium (Zr), which is stable at a high temperature. The dataset is used to build a Euclidean symmetry equivariant neural network (E3NN) model to map the energy landscape of the system as a function of the atomic displacements from the ideal lattice. Given that the framework of the network uses physical concepts which allows for the ability to train with less data, we generate predictions, allowing us to compare them with our dataset.
