We present a code allowing to evolve three-dimensional self-gravitating collisionless systems with a large number of particles N >= 107. FLY (Fast Level-based N-bodY code) is a fully parallel code based on a tree algorithm. It adopts periodic boundary conditions implemented by means of the Ewald summation technique. FLY is based on the one-side communication paradigm and was originally developed on a CRAY T3E system using the SHMEM library and it was ported on SGI ORIGIN 2000 and on IBM SP. FLY (http://www.ct.astro.it/fly/) version 1.1 is an open source freely available code. FLY data output can be analysed with AstroMD, an analysis and visualization tool specifically designed to deal with the visualization and analysis of astrophysical data. AstroMD can manage different physical quantities. It can find out structures without well defined shape or symmetries, and perform quantitative calculations on selected regions. AstroMD (http://www.cineca.it/astromd) is a freely available code.
