4 Dec 2013 U(S,V,N) total energy is a function of several terms forces are the derivatives of the total energy energy and momentum conservation. QM region is fixed boundary problems can appear force convergence problem at the boundary or even in the centre of QM region boundary problem can be eliminated.
It implements a variety of interatomic potentials and tight binding quantum mechanics, and is also able to call external packages, and serve as plugins to other software such as LAMMPS, CP2K and also the python framework ASE. Various hybrid combinations are also supported in the style of QM/MM, with a particular focus
4 Nov 2017 Hi 1) you can use counter ions or let CP2K automatically use a uniform background charge. Both approaches have their unique problems. 2) Standard QM/MM works with a fixed QM system. This is for some good reason. The adaptive QM/MM is an innovative approach to avoid some shortcomings of this
Energy is not conserved (although the QM/MM energy from the large QM region calculation is reported) so a proper thermostat (i.e. massive, and able to handle dissipation, such as Adaptive Langevin (AD_LANGEVIN)) must be used. For some propagation algorithms (NVT and REFTRAJ MD ensembles) algorithm is
13 Sep 2013 We present reaction free energy calculations using the adaptive buffered force mixing quantum mechanics/molecular mechanics (bf-QM/MM) method.1 The bf-QM/MM method combines nonadaptive electrostatic . The adaptive buffered force QM/MM method in the CP2K and AMBER software packages.
3 Feb 2015 Abstract. The implementation and validation of the adaptive buffered force (AdBF) quantum-mechanics/molecular-mechanics (QM/MM) method in two popular packages, CP2K and AMBER are presented. .. Possible keyword values are specified in the built-in CP2K documentation. The fixed core region

G otz, of Nose Hoover part of thermostat Some additional keywords that were used for testing runs are listed in the AMBER manual. which is not adaptive, so only the
21 Jun 2012 The difference-based adaptive solvation quantum mechanics/molecular mechanics (adQM/MM) method (J. Chem. Theory Comput.2009, 5, 2212) as implemented in the Amber software was applied to the study of several chemical processes in solution. The adQM/MM method is based on an efficient
18 Sep 2014 Abstract: The implementation and validation of the adaptive buffered force QM/MM method in two popular packages, CP2K and AMBER are presented. The implementations build on the existing QM/MM functionality in each code, extending it to allow for redefinition of the QM and MM regions during the
The implementation and validation of the adaptive buffered force QM/MM method in two popular packages, CP2K and AMBER are presented. The implementations build on the existing QM/MM functionality in each code, extending it to allow for redefinition of the QM and MM regions during the simulation and reducing
