Project Summary

NOTE: New Download procedureTo facilitate version control, we have started uploading new versions and checking out the latest version with svn. To download the latest version of the code you can type:

svn checkout http://celeste.googlecode.com/svn/trunk/celeste celeste

from the directory where you want the code to be. A new directory will be created from the directory you are in called celeste with the code inside.

The old procedure for downloading the code still works. For now svn is experimental.

More details in Installation

If you use CELESTE3D, we request that you inform us and reference the papers listed belowOur work is done for Science and for the benefit of Humankind (without implying any intention of restricting access to benevolent aliens). So we only require that you give credit explicitly to the code Celeste3D and that you reference the three papers listed below, if you use in any way the codes provided here or the results of them for your publications. We ask also to be notified of any published material using the code (just so that we can reference it).

If you require assistance in using the code, than it might become appropriate (and this will depend from case to case) to have a more formal collaboration, including co-authorship of the outcome of the collaboration.

An implicit method for electromagnetic plasma simulation in two dimensions by Brackbill and Forslund

Kinetic approach to microscopic-macroscopic coupling in space and laboratory plasmas by Lapenta, Brackbill, Ricci

The research on the codes presented here has received funding from the European Community's Seventh Framework Programme (FP7/2007-2013) under the grant agreement n° 218816 (SOTERIA project, www.soteria-space.eu).

Description of the code Celeste 3DKinetic plasma simulation typically requires to handle a multiplicity of space and time scales. The implicit moment particle in cell PIC method provides a possible route to address the presence of multiple scales effectively. Here, a new implementation of the implicit moment method is implemented in the code: CELESTE3D code, a fully electromagnetic and fully kinetic PIC code, based on the implicit moment method. The code has been in use for a number of years. A number of input files for different benchmarks of CELESTE3D are included to show the typical application.

The Implicit Moment MethodA description of the numerical method in CELESTE3D is available on these published papers:

on Journal of Computational Physics An implicit method for electromagnetic plasma simulation in two dimensions by Brackbill and Forslund

on Physics of Plasmas Kinetic approach to microscopic-macroscopic coupling in space and laboratory plasmas by Lapenta, Brackbill, Ricci a recent writeup is freely available from arXiv:

arXiv paper on the method used in CELESTE3D

The Special Relativity Implicit Moment MethodThe implicit moment method has been extended also to plasmas treated with special relativity:
