The scientific organizing committee of the NORDITA
Astrophysics Code Comparison Workshop would like to invite
you to a 5-day
workshop from August 6th to 10th, 2012, at Stockholm, Sweden.
Owing to their large length scales, most astrophysical objects have very large
Reynolds numbers and are indeed observed to be turbulent. Given that laboratory
experiments are usually not available and analytical techniques are very limited,
numerical simulations become the most valuable tool to study these complicated
The developments and applications of state-of-the-art numerical codes have
driving important advances in all branches of astrophysics. However, as these
astrophysical codes become more complex, the barrier to entry rises. As a
consequence, students and young researchers often use the codes as "black
boxes" without deep understanding of their underlying algorithms. This lack of
understanding may ultimately lead to confusion in the field and may even slow
down progress in astrophysical research. Even worse, applying algorithms to
regimes in which they break down can lead to scientifically false results.
By bringing together renowned experts from around the world, the main
the NORDITA Astrophysics Code Comparison Workshop are to 1) provide a suit of
clear and simple test cases, 2) clarify existing misunderstandings in the literature,
3) compile a rule-of-thumb list useful to astrophysicists, and 4) find ways to
improve existing numerical algorithms.
We are planning to focus on hydrodynamic and magnetohydrodynamic
turbulence, although actual topics may vary depending on the participants. In
order to make this mini-workshop useful, we will setup an on-line forum once the
registration is closed (June 1, 2012). The participants can start discussing a
preliminary set of test problems. The workshop (Aug 6--10, 2012) will consist of
morning talks/reports, and afternoon discussion/numerical experiments.
If you are interested in participating in the workshop, please fill and submit
application form located at <http://goo.gl/jDIXy>. The registration deadline is on June
1st, 2012. There is no registration fee. You will be informed by the organizers
shortly after the application deadline whether your application has been approved.
