I'm interested in doing simulations with large numbers of particles and need a good n-body code. Are there any out there in the public domain that are open-source and what are their strengths and weaknesses. I'm interested in all types of codes, ones that can be run on a multi-core desktop for basic simulations and also ones that can be run on large parallel clusters (I have access to both).

For each entry please provide a link and a brief summary of the nature of the code and strengths of the software. The goal here is to provide a reference list for those interested in the topic

Expert Solution

First of all, I do not have any experience with this, I am an Astronomy hobbyist at best. So I am just going to present what I found with minimal comment at this time. I found this web page that links to several programs: http://nbody.sourceforge.net/ They link to the University of Washington and their n-body shop. I don't know what your status must be to get that software (a student perhaps).

The first link also lists these sources:

Other Astrophysical N-body projects

Integration with work by others is very desirable. Here are some projects we know about. To let us know about others by submitting a new item to the SourceForge Bugs Tracker.

The Nbody Shop - The first software released here has come from this group. The TIPSY nbody visualization program is available from this group.
NChilada - a project to create a parallel visualization and analysis package.
Hubble in a Bottle - a High performance parallel visualization tool. Hosted on Sourceforge.
NEMO - a stellar dynamics toolbox.
GADGET - a freely available parallel code for cosmological N-body/SPH simulations.
SUNRISE - a GPL program to do radiative transfer imaging of cosmological or galactic SPH simulations.
AMIGA - a freely available (GPL) shared memory parallel adaptive mesh code that also includes a group finder.
astro-sim.org - a community site with pointers to astrophysical CFD and n-body codes.

Some additional links that I have found:

I hope this series of links gives you what you want.

I need it in java. Write a program that will print if n numbers that the user will input are or not within a range of numbers. For that, your program needs to ask first for an integer number called N that will represent the number of times that will ask for other integer numbers. Right after, it should ask for two numbers that will represent the Min and Max for a range. Lastly. it will iterate N number times...

Hello. I'm trying to write down java code making stars whose numbers are determined by user input on the console (each star's data are stored in ArrayList). the class extends JFrame and its color, size(Zoom in and Zoom out), and location are changing every time. Moreover, its angular rotation is changed at a certain determined degree. Does anyone know how to write down the java code of this question?

Imagine a gas of N spherical particles that are free to distribute throughout either a large volume or a small one.

Imagine a gas of N spherical particles that are free to distribute throughout either a large volume or a small one. Why does the gas spread out into a large volume? The tendency to spread out is pressure and can be explained in terms of multiplicity or increased probability. To illustrate this, let's create a simpler model that we can visualize, solve exactly, and will illustrate the essence of the problem without the mathematical complexity. For each of the following,...
