This tool provides access to the density functional theory code !SeqQuest via nanoHUB.org. !SeqQuest is developed at Sandia National Laboratories by Dr. Peter A. Schultz of the Multiscale Dynamic Materials Modeling Department and collaborators. Using !SeqQuest, this tool enables users to calculate the total energy, atomic forces and stress for molecules, wires, slabs and bulk systems.
SeqQuest, a density functional theory code from Sandia National Laboratories.
- Graphical Interface: Ravi Vedula, Gregory Bechtol, Benjamin Haley, and Alejandro Strachan
- Simulation Engine: Peter A. Schultz, Sandia National Laboratories and collaborators. http://dft.sandia.gov/Quest/
