Dear OOF Users -- A new version of OOF2, 2.1.19, is now available on the OOF2 website, http://www.ctcms.nist.gov/oof/oof2 This version fixes a rare output bug and adds some new features, including von Mises stress output and a generalized plane strain, which sets epsilon_zz to a non-zero constant value. Thanks to Adam Creuziger and Michael Weiss for bug reports and feature requests. 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.
