Foil 4 Particle Applications - Ordinary Differential Equations (ODE's)

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95/96/97. by Nancy McCracken and Geoffrey C. Fox
Consider Models of physical systems represented as sets of particles rather than densities (fields) evolving over time
Examples:
  • the solar system
  • an electrical or electonic network
  • a globular star cluster
  • the atoms in a crystal vibrating under interatomic forces
  • the molecule rotating and flexing under interatomic force
Laws of Motion are typically ordinary differential Equations
Ordinary means differentiate wrt One Variable -- typically time
