N-Body Modeling and Technical Computing Resources

Someone asked for a list of resources on N-Body modeling. I had a bunch of links in my favorites so here they are. I also threw in some more on technical computing and writing high performance code.

N-Body modeling

Here’s a list of resources on N-body modeling starting with some introductory material and getting more specific as you go down the list. If your interested I’d definitely recommend the tutorials in The Art of Computational Science.

Introduction to the N-body problem

The Art of Computational Science

N-body simulations (gravitational) – Scholarpedia

On Simulations of Galaxy Dynamics and Their Application to Physics Education

N-body-Particle Simulation Methods

Runge–Kutta methods – Wikipedia

 The XStar N-Body Solver Theory of Operation

Gravitational N-Body Methods (introductory chapter) – Sverre Aarseth

Sverre Aarseth’s Institute of Astronomy N-Body and Downloads Page

Specific implementations like tree codes

Most implementations seem to use hierarchical (tree) based implementations – first implemented by Barnes (see below).
