Welcome to astro-sim.org!

astro-sim.org is an open community for users and developers of astrophysical simulation codes.

astro-sim.org is intented to be the place to look first for information and requests for help about astrophysical simulations. By now, every research group seems to try and write its own code, which may be reasonable for very specialised problems or educational purposes. But way too often the reason for that is simply that people don't know about what codes there are... Or cannot distinguish between a suitable and an inappropriate code due to the lack of information.
You can't spend your time finding and reading through dozens of websites and publications to find a code or the description of an algorithm that will solve your problem. But you can look at one to find it at a glance.

astro-sim.org is meant to be that website!

Find what you're looking for!

There's a number of ways to find what your looking for:

• The News page will give you the latest update on new codes, conferences and other events that may be of interest.
  If you want to be able to post news yourself, e.g. if you are (co-)developing a code or organizing meetings frequently, or just feel like seeking news items and posting them, you can email to the administrator and we'll make you an "author" so you will be able to provide articles to the news-section.
• The Free Codes section will describe (hopefully) all freely available simulation codes and give short introductions about the numerical techniques used in computational astrophysics. It will also cover scripts and other little helpers related to simulation codes, visualisation, data analysis etc.
• Tools and Libraries will help you to write your programs. No need to reinvent the wheel.
• The Visualisation section will give you an introduction to a growing number of free and comercial visualisation tools, libraries etc.
• The Data Analysis section will give you an overview of tools made for analysing simulated data. Some of it is code independent, some will be limited to a special file format as profuced by a code.
• In the Forum you can post questions, specially when you are just starting your career as a simulating astronomer. So don't be afraid of what you might call "stupid questions". There is no such thing! But also experienced users are wanted to enter and discuss their topics on this platform. It may help others! And please take a minute to answer beginners questions as well!
  You need to register to post to the forum. That's to protect you, the sensible user, from spam.
• Finally, the Links will guide you through the world wide web to seek and find information you haven't found here.

This website is non-profit. That means that people spend their free time on enhancing it, finding the latest news, moderating the forums etc. You will help a lot to email us any information that fits. You wrote a code? Write us! You're organising a conference or workshop? Write us! You found some wrong information? Write us! You don't know how to install Linux on your laptop? Mmmhhh... don't write us ;-)
