...It was used by the American Ephemeris and the Astronomical Almanac into the 1980's to compute the daily positions of the Sun. This Theory is a semi-analytic model which expresses quantities as a trigonometric series with numerical coefficients. This type of model produces a compact computer function which has enough accuracy to be useful to most users. My goal is to create a model using C which will reproduce exactly the results published in the Astronomical Almanac for the years 1981, 1982 and 1983.

galaxie chung is a galaxy numerical simulation experiment i have written in fast compiled freebasic for calculation and openGL for displaying. the galaxy is modelized as a gaz of stars submited to gravitation. Can run on an ordinary pc notebook.

As of August 2018 Spheral++ has moved to Github -- please see the current repository at https://github.com/jmikeowen/spheral We are leaving a frozen version here on SourceForge for historical reasons. Spheral++ provides a steerable parallel environment for performing coupled hydrodynamical & gravitational numerical simulations. Hydrodynamics and gravity are modelled using particle based methods (SPH and N-Body).

Imagine Numerical Recipes in the 21st century. Fast object-oriented Java code for numerical analysis, with a special focus on astronomical application (coordinate conversions, WCS projections etc.)

This project has be renamed to jnum and moved under the crush-software project. No further SVN commits here...

The software simulates the motion of the solar system by different numerical methods. On start, the software expects the input file planeten.txt in the same folder. This file should contain the desired initial conditions. The separator may be adjusted via the file settings.ini.

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.
