OOF Newsletter #11 (March 2005) Dear Colleagues -- The OOF development team is proud to announce the next beta release of OOF2, version 2.0 beta 4. Source code and installation instructions are available at http://www.ctcms.nist.gov/oof/oof2.html A list of changes since the previous release is available at http://www.ctcms.nist.gov/oof/oof2changes.html Electric fields have been added, along with static dielectric and piezoelectric material properties. The electrical aspects are preliminary: piezoelectricity is working, but mechanical interactions between space charges are not yet implemented. A new "Relax" algorithm has been added to adapt mesh skeletons to the material geometry. It's like the "Anneal" algorithm, but is deterministic instead of probabilistic. We have made numerous bug fixes and a few user interface changes. In addition, new versions of the OOF1 programs, oof and ppm2oof, are available at http://www.ctcms.nist.gov/oof/download/ oof and ppm2oof can now save their data in the OOF2 format. Existing data files can be read by OOF1, saved as OOF2 data files, and then read by OOF2. When loading data from OOF1, use OOF2's --script command line option or the Script command in the File/Load menu. Because this is a beta release of OOF2, bugs may still remain in the code. Please send bug reports to oof_bugs@ctcms.nist.gov For more details, see the "Bug Reports" section of the OOF2 web page. Thank you to everyone who has submitted bug reports. Suggestions for future additions to OOF2 are always welcome. A modified version of OOF1, capable of writing OOF2 data files, will be available soon. We are making good progress on the OOF2 manual and hope soon to have a preliminary version of it on the web. Sincerely, The OOF2 team, Steve Langer Andrew Reid Seung-Ill Haan Edwin Garcia oof_manager@ctcms.nist.gov
