WOMBAT - Code Request
Why use WOMBAT?
There are many astrophysical fluid codes available, such as AstroBEAR, ATHENA and PLUTO (plus many more). Each code is likely constructed in a way that targets a specific audience and purpose. We encourage anyone interested in astrophysical simulations to consider all of these very powerful codes (including WOMBAT) and make the choice best for your research.
The goals of WOMBAT was for it to be a well scaling (beyond 10,000 cores) code that is simple to use and makes very efficient use of modern multi-level cache processors. For just MHD simulations, WOMBAT is a good choice if speed and large problem size are important. One example is turbulence modeling, where potentially tens of thousands of time steps are needed. Another good application is a parameter study, where a wide grid of calculations is needed. WOMBAT also has many unique features for solving the evolution of cosmic rays, an implementation of special relativistic MHD with the widest possible dynamic range, and total energy conserving gravity. The upcoming WOMBAT paper will go through many of these methods in detail.
WOMBAT is currently available by request only. Please use our contact form to make your request. We can help you decide if WOMBAT is the right choice if you indicate the nature of the simulations you wish to run and type of machines available to you.
WOMBAT is currently in version 1.0. This version is in bug-fix only maintenance as our efforts have shifted to work on version 2.0. All physical modules and solvers in version 1.0 have been subjected to a wide range of tests and verifications. Nevertheless, we can make no guarantee that the code is without error, and it is important that all users identify tests that can convince them of the code's accuracy. As any numerical methods in fluid dynamics are only approximations of the solutions to the governing equations, users must familiarize themselves with the limitations of such methods.
We are very happy to provide WOMBAT to interested researchers with the caveat that it is not possible for us to provide unending support for all problems and enhancement requests a user might encounter. There are only three primary developers for WOMBAT. That being said, it is our hope to make WOMBAT available to a wide audience and see its use increase for a variety of astrophysical problems. We will do everything within our ability to respond to questions and bugs.
