Web3.4.2 Automatic geometry optimization with VASP It is generally the case that the equilibrium geometry of a system is the one that minimizes the total energy and forces. Since each atom has three degrees of freedom, you can quickly get a high dimensional optimization problem. WebJul 5, 2024 · The main structural output of a geometry optimization in Castep is in the file with the ".geom" extension. That file contains blocks with lattice parameters and atomic positions at each step of a geometry optimization, and the final structure would be the last block in the file. More details about this file can be found in the Castep manual here.
WebGeometry Optimisation with CASTEP Chris Eames This document (which is available for download as a pdf file) is a basic introduction to the methodology of performing geometry optimisation calculations with the CASTEP program.
