Abstract

This tool provides access to the density functional theory code SeqQuest via nanoHUB.org. SeqQuest is being developed at Sandia National Laboratories by Dr. Peter A. Schultz of the Multiscale Dynamic Materials Modeling Department and collaborators. Using SeqQuest the tool enables users to calculate the total energy, atomic forces and stress for molecules, wires, slabs and bulk systems.
