Dear OOF Users: Yet another new version of OOF2, 2.0.5a11, is now available at the OOF website, http://www.ctcms.nist.gov/oof/oof2/index.html#download This release fixes serious bugs in the piezoelectric calculations. If you are using OOF2 on piezoelectric microstructures, you should download the new version and repeat your calculations. There is no need to upgrade to 2.0.5a11 if you aren't using piezoelectricity. We apologize for the inconvenience. Sincerely, The OOF Developers Andrew Reid Valerie Coffman Gunay Dogan Steve Langer
