MM是Molecular Mechanics的简写,你在文献上看到的molecular dynamics (MD)说的是分子动力学,MM指的是一类计算能量的方法,而MD是一类研究体系动态过程或者体系系综平均的算法。MD可以基于MM,也可以基于QM。

QM/MM free-energy perturbation and other methods to estimate ligand-binding affinities. Olsson, M., 2018 feb, Lund: Lund University, Faculty of Science, 

The point charges correspond to classical force field atoms (each sphere representing a core and shell) and an outer layer of external point changes fitted to reproduce the electrostatic influence of the bulk material. Powerful Quantum Mechanical/Molecular Mechanical (QM/MM) approaches are of the auxiliary function sets and their primitive Hermite Gaussian form [12]. On the practical aspect, performing accurate QM/MM calculations on protein many problems in the preparation of the input so check if your gaussian input has   QM/MM calculation of alanine-tripeptide in water In this tutorial, we illustrate how to The input files for GENESIS and GAUSSIAN, as well as script files to  This implementation is stable even for large Gaussian basis sets with diffuse exponents, and is thus appropriate when the QM region is described by a correlated  GaussView would be the fastest option to prepare input files for QM/MM Afterwards just choose Calculate->Gaussian calculation Setup…, in the Method. The ONIOM method is a computational approach developed by Morokuma and co-workers. Codes that support ONIOM[edit]. Gaussian · NWChem. See also[ edit].

ONIOM is a hybrid method that enables different ab initio or semi-empirical methods to be applied to different parts of a molecule/system in combination to produce reliable geometry and energy at reduced computational cost. The ONIOM computational approach has been found to be particularly useful for modeling biomolecular systems as well as for transition metal complexes and catalysts.

molUP quickly identifies the positive and negatively charged molecules in the system (blue and red surfaces) After the assigning of ONIOM layers, this interface can also be used to estimate the charge of each layer (required for any QM/MM calculation).
