DFTB+ Step

Description

A SEAMM plug-in for DFTB+, a fast quantum mechanical simulation code.

This plug-in provides a graphical user interface (GUI) for setting up simulations using DFTB+ quantum mechanical simulation software package. DFTB+ does quantum mechanical simulations similar to standard density functional theory (DFT) for molecules, crystals and materials. The simulations are carried out in an approximate way using the Density Functional based Tight Binding method (DFTB), which is typically about two orders of magnitude faster than traditonal DFT.

Features

• The selection and use of any of the parameter sets found at the DFTB website.

• Single-point energy calculations

• Structural (geometry) optimization

At the moment the plug-in only handles molecular (non-periodic) systems. Periodic systems will be added in an upcoming release.
