Scientific Computing FAQ: N-Body and Particle Simulation

N-Body and Particle Simulation

N-Body Simulation Web Sites

Amara Graps' N-Body paper discusses N-Body problems. N-body problems occur in fields such as cosmology, solar system dynamics, molecular dynamics, and plasma physics. My summary of N-body simulation methods contains info on the following methods: Particle-Particle (PP), Particle-Mesh (PM), Particle-Particle/Particle-Mesh (P3M), Nested Grid Particle-Mesh (NGPM), Tree-Code (TC)- Top Down, Tree-Code (TC)- Bottom Up, Fast-Multipole-Method (FMM), Tree-Code Particle-Mesh (TPM), Self-Consistent Field (SCF), and the Symplectic Method. I also list Internet sites for research groups, some papers, some code, and other NBody-related links. It is at:

N-Body Simulation Software

Peter Teuben's NEMO is an extendible Stellar Dynamics Toolbox. It has various programs to create, integrate, analyze and visualize N-body and SPH like systems. In addition there are various tools to operate on images, tables and orbits, including FITS files to export/import to/from other astronomical data reduction packages. We also advertise other software packages , which work on similar problems.
