OOF Users -- A new version of OOF2, 2.1.18, is now available on the OOF2 website, http://www.ctcms.nist.gov/oof/oof2/ This version adds a new method for automatically grouping pixels. Material constants and orientations to be included in output files, making it easier to correlate local fields and fluxes with material parameters. For details, see the change log at https://www.ctcms.nist.gov/oof/oof2/changes.html. Please let us know if you encounter any problems. Report bugs to oof_bugs@nist.gov and send other comments to oof_manager@nist.gov. We especially like to hear about how you're using OOF2 and OOF3D now and how you'd like to use it in the future. Sincerely, The OOF developers Steve Langer Andrew Reid Gunay Dogan
