febioThe MRL Software development team is excited to announce the arrival of version 1.4 of FEBio (Finite Elements for Biomechanics).

Download FEBio 1.4

FEBio is an open-source finite element package, specifically designed for solving problems in the field of computational biomechanics. This new version includes some major changes and contains a number of new and exciting features. Some of the noteworthy changes and additions are listed below.

  • Improved data-output options. A new binary plot file format was designed to address some of the limitations of the old format. The format is extendable and flexible and allows for improved interaction between FEBio and its post-processor PostView. The contents of the new binary file can be completely defined by the user. Additional output options are also available for data logging.
  • New analysis modes were introduced: heat transfer, biphasic, and biphasic with solutes.
  • New constitutive models include Fung orthotropic, exponential power-law, continuum damage models, ellipsoidal fiber distribution and solid mixtures.
  • Improvements to the existing contact algorithms and a new contact formulation that takes into account solute transport across the contact interface.
  • "Under the hood", FEBio has undergone some major structural changes. The end-user may notice a significant improvement in performance for certain problems. The developer will find that customization of FEBio is easier than ever.
  • Expanded FEBio prompt for more interaction during runs.
All documentation has been updated and can be downloaded from the MRL FEBio Website. The release notes have been updated and can also be downloaded separately from the Documentation tab of the software page. The svn logs have been added to the Help directory of the download. These can be useful for developers who want to know which files in the source code were effected by particular changes. Online versions of the manuals are also available on our FEBio Help Site. FEBio's supporting software, PreView and PostView, have also undergone some major improvements, making it easier than ever to create, define and analyze finite element models with FEBio. These packages can also be downloaded from the MRL Software Site.

We encourage you to report any problems or questions on the MRL Software Forum.

We also would like to take this opportunity to thank our ever-growing user base for helping us make FEBio a great tool for computational biomechanics. As always, we would really appreciate any feedback that you may have to help us improve FEBio.

Finally, if you are an FEBio user please tell us about your publications with FEBio. As part of our effort to track the impact of the FEBio software suite, we have assembled a list of all publications that have used or referenced FEBio. This information will be very important for our application to renew the FEBio NIH grant, due at the beginning of November, 2011. Our current list of FEBio publications can be found on the Publications tab at the FEBio Website. If you have publications (research articles or abstracts) that are published, "in review" or "in preparation" that are not on the list, please send us the reference information by October 21, 2011 so that we may include it in our Progress Report.

Kind Regards,
