Leiden Classical is a distributed computing

Distributed computing

Distributed computing is a field of computer science that studies distributed systems. A distributed system consists of multiple autonomous computers that communicate through a computer network. The computers interact with each other in order to achieve a common goal...

 project run by the Theoretical Chemistry Department of the Leiden Institute of Chemistry at Leiden University

Leiden University

Leiden University , located in the city of Leiden, is the oldest university in the Netherlands. The university was founded in 1575 by William, Prince of Orange, leader of the Dutch Revolt in the Eighty Years' War. The royal Dutch House of Orange-Nassau and Leiden University still have a close...

. Leiden Classical is part of the BOINC system, and enables scientists or science students to submit their own test simulations of various molecules and atoms in a classical mechanics

Classical mechanics

In physics, classical mechanics is one of the two major sub-fields of mechanics, which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces...

 environment.

Joining the project

Participation is possible via the BOINC manager. Using this software one can create an account in the project. Then someone can make a model of a dynamic system and simulation participating run. There are several models possible, to interactions between molecules or planets.

User Submitted Calculations

To create a personal calculation, your model must have 6 defined variables:

1. Colors of your molecules
2. Box in which the model is run
3. Number of particles in the simulation
4. Interaction between the particles
   1. Gravity
   2. Coulomb force
   3. Lennard-Jones interaction
   4. Morse interaction
      Morse potential
      The Morse potential, named after physicist Philip M. Morse, is a convenient model for the potential energy of a diatomic molecule. It is a better approximation for the vibrational structure of the molecule than the quantum harmonic oscillator because it explicitly includes the effects of bond...
      
      
   5. Rydberg interaction
   6. Harmonic spirit
   7. Harmonic bending
   8. Recurrent torsion interactions
5. Distance conditions
6. Confirmation parameter(s)
