N -Body / Particle Simulation Methods Amara's Recap of Particle Simulation Methods ("ARPSM" !!) My own experience with N-body simulation methods are with schemes using direct integration of forces ("Particle Particle" methods), and also with the symplectic methods. When a discussion in August 1995 on the sci.math.num-analysis newsgroup about N-body/Particle simulation methods caught my attention, I wrote this article to keep track of the different schemes (too many acronyms!), and to learn what researchers in the field are using today.

Home Applications ORSA@work ScreenShots ... About News Announcing SurfaceCoverage Tool May 12 2008 We've released a new tool: SurfaceCoverage . Please follow the link for more details. New Tool Jul 1 2007 After over two years of quiet but active development, we're releasing today the first application based on the new ORSA code base: RendezvousWithVesta . This tool has been developed in support to the NASA DAWN mission , and allows to accurately simulate the dynamics of a spacecraft orbiting the asteroid (4) Vesta . It's main purpose is to determine what is the orbit of the DAWN spacecraft that provides the best coverage of Vesta's surface. This orbit will depend on Vesta's physical parameters, so it cannot be fully determined yet, as we don't know what is Vesta's mass with sufficient accuracy today. Nevertheless, by using RendezvousWithVesta the DAWN Science Team can investigate the possible effects of Vesta's mass on the overall surface coverage, and users in the general public are welcome to download the tool and experiment with it, and possibly collaborate with us on the ORSA-tools mailing list . Read more about it at the RendezvousWithVesta page and download it here RendezvousWithVesta is the first ORSA tool based on the Qt4 framework , that permits to easily develop open-source, GUI based applications and port them to Linux, Mac and Windows. Other improvements include the possibility to import/export
