Geometric relaxation
WebGeometry optimization. A geometry optimization is the process of changing the system’s geometry (the nuclear coordinates and potentially the lattice vectors) to minimize the total energy of the systems. This is typically a local optimization, i.e. the optimization converges to the next local minimum on the potential energy surface (PES ... WebOct 30, 2009 · 18 - Geometric relaxation.
