HOOMD is going blue!
HOOMD's lead developer has graduated and moved on to a position at the University of Michigan, and the center of HOOMD development is moving with him. Due to technical reasons regarding licensing, a name change must be part of the move. Thus HOOMD development will continue under the name HOOMD-blue! It stands for Highly Optimized Object-oriented Many-particle Dynamics -- Blue Edition.
If you are familiar with the language used commonly in open source projects, this is technically a fork of the original HOOMD project. For all practical purposes, however, it actually is not a fork as we have the same developers continuing to work on the code as if nothing happened. No major changes to the roadmap are planned and, if anything, the development effort will only accelerate after this move. Our apologies for any confusions this might cause, but such changes are inevitable with young projects developed by graduate students.
The new web URL for HOOMD is at http://codeblue.umich.edu/hoomd-blue/ and the server combines that directly with Trac and SVN hosting for the project at https://codeblue.umich.edu/hoomd-blue/trac/ and https://codeblue.umich.edu/hoomd-blue/svn/ respectively. The old website and SVN will be left up for a few months for continuity before they are taken down.
A new feature we are proud to offer on this Trac web is the ability for users, not just developers, to register accounts with the system. To do this, go to the Trac web page, click the register link in the upper right and follow the onscreen instructions. After verifying your e-mail address with the system, you will be able to edit and add to the wiki, post new tickets and add comments to existing tickets.
Getting this new page operational has been the major blocker delaying the release of 0.8.2. Now that we are up and running, expect this next packaged release soon!

Hotfix to HOOMD 0.8.0
A serious issue was discovered in the windows builds of HOOMD 0.8.0. Any use of dump.dcd would result in the hoomd executable crashing. This issue is fixed in hotfix binaries labeled version 0.8.0.1. Users compiling from the source tarball will need to apply the following diff: r1581.
Linux and Mac users are unaffected.

HOOMD 0.7.1 Released
A critical bug that might cause incorrect results in simulations with tiny box sizes was just discovered. HOOMD 0.7.1 is being released to fix this issue. All users should upgrade immediately. Large simulations with 1000's of particles are not effected, only tiny simulations with a few 100 particles experience the bug.
Changes since 0.7.0
- Fixed a bug where systems with box dimensions less than 3*(r_cut+r_buff) would run incorrectly and without producing an error.
- Fixed a bug that prevented extremely low density systems from being run.
We are committed to providing an accurate, as well as fast, simulation software and have a stringent battery of automatic unit tests to verify the correct calculation of every force and integration step in HOOMD. This critical bug slipped through simply because none of those test cases was set in such a tiny box size.

HOOMD 0.7.0 Released
HOOMD 0.7.0 is finally done!
The biggest change is the inclusion of the job scripting system. With it, configuring simulations in HOOMD is a snap. See the quick start tutorial for in introduction. HOOMD 0.7.0 has also been thoroughly tested for stability and accuracy. We have a 2-GPU machine that has been running research simulations 24/7 for weeks now without a single crash or other problem.
In other words, HOOMD is now ready to be used by anyone for serious research, download it now.
Changes since 0.6.0:
- Job scripting system
- User documentation
- Stability improvements
- Energy logging
- File conversion scripts
- GPU selection
- Advanced initial configuration generator (for polymers)
- Particle types named by strings
- Bug fixes
... and much, much more. See the change log for a more detailed list.
