Description
Grand Canonical Adaptive Resolution Scheme (GC-AdResS) is getting more recognition throughout the scientific community. The main aspect is to couple two simulation boxes together and combine the advantages of classical atomistic simulations with those from coarse gained simulations. The goal of the pilot project is to develop a library or recipe with which GC-AdResS can be implemented in any MD Code. Our current focus is adjusting the implemented Version of GC-AdResS in GROMACS. The long-term goal of this project is to promote and stimulate the community to use it as a tool for multiscale simulations and Analysis.
Development Plan
List of Tasks
- Set up a new scheme in GROMACS (in the Moment Version 5.1.0) and adjust the Fallout in the form of adjusting the thermodynamic force interpolation
- Set up a new scheme in ESPRESSO++ in cooperation with the Developers in Mainz
- And finally generalizing those schemes
List of Modules
- Abrupt GC-AdResS: A new and more general implementation
- Radial Distribution Functions for GC-AdResS
- Abrupt-AdResS: Forcecap
- Thermodynamic Force Calculator for Abrupt AdResS
- Local thermostat adaption of the Abrupt GC-AdResS scheme
- Tools for AdResS
- Velocity-Velocity autocorrelation function for AdResS
- Dipole-Dipole autocorrelation function for AdResS
- Energy (AT)/Energy(interface) ratio: Necessary condition for AdResS simulations
