Aid in the design, configuration and testing of various SAP modules: Primarily QM, MM, WM, and PP with secondary emphasis on SD SAP WM/MM ** SAP WM is a Must.** Internal Business Application Consultant SAP WM/MM (QM would be an advantage) being responsible for development, improvement, roll-out and support of group wide The hybrid QM/MM approach is a molecular simulation method that combines the strengths of ab initio QM calculations and MM approaches, thus allowing for the study of chemical processes in solution and in proteins. The QM/MM approach was introduced in the 1976 paper of Warshel and Levitt. They, along with Martin Karplus, won the 2013 Nobel Prize in Chemistry for "the development of multiscale models for complex chemical systems". If the QM and MM regions are separate molecules, having non-bonded interactions only might be sufficient. If the two regions are parts of the same molecule, it is necessary to describe the bond connecting the two sections.

The active center is treated at the QM level and the surroundings is treated at the MM level called secondary subsystem, or SS) at the MM level. The QM/MM energy for the entire system (ES) can be formally defined by E(QM/MM;ES) = E(QM;PS)+ E(MM;SS) +E(QM/MM;PS|SS), (1) QM/MM geometry optimizations in Chemshell are documented in the Chemshell manual. Using ORCA as the QM code in QM/MM calculations just means that you have to modify the qm_theory part. As always in QM/MM, setting up the system and the MM region is the complicated part.

Mechanical and electric embedding are contrasted. Then we review some recent tests of QM/MM methods and QMMM Hybrid Quantum Mechanics/Molecular Mechanics In QM/MM, part of the system is treated using quantum mechanical (QM) calculations (very time-consuming), while the remainder of the system is treated by using standard molecular mechanics (MM) force fields. GROMACS provides QM/MM capabilities by interfacing with external QM software.
