Description

This Floe is the third part of the CSP protocol developed by OpenEye. The input should be previously predicted or experimental crystal structures and outputs QM optimized crystal geometries.

This floe does the following: optimization of crystal geometry and unit cell, and single point rescoring with a higher level of QM, needed for accurate ranking of crystal structures. At the end of this workflow for each structure lattice energy and sublimation enthalpies are computed.

Our approach is based on dimer expansion of crystal energy, which allows massive parallelization of the computation, and significant reduction of wall clock time.
