View Full Version : FEBio - Finite Elements for Biomechanics

09-07-2007, 06:28 AM
It is my pleasure to announce the 1.0 release of the software FEBio,
“Finite Elements for Biomechanics”. FEBio is a nonlinear finite element
software package that is specifically designed to address problems in
computational biomechanics. Some of the features of note include
capabilities for contact, rigid bodies and kinematic joints, nonlinear
anisotropic constitutive models, simulation of active contraction,
poroelasticity, element formulations for nearly-incompressible materials
and parallel solution of the linear system of equations. After extensive
testing in our lab and with our collaborators, we are happy to offer
this free software to the research community.

FEBio is available through our laboratory our web page at:
You can preview the User’s Manual here:

FEBio is currently available for WindowsXP, MacOS/X, Suse Linux (64 bit
Opteron/Athlon64) and SGI Altix (64 bit Itanium2). We would be happy to
port FEBio to other Unix/Linux platforms. The FEBio distribution
includes the User’s Manual, Theory Manual and several test problems to
verify proper operation.

We are also pleased to announce the 1.0 releases of PreView and PostView
– FE preprocessing and postprocessing software packages that support the
use of FEBio, as well as other FE solvers. These packages are available
at the same web page.

We have big plans for FEBio. Our goal is for FEBio to be the first and
best choice for finite element analysis in solid biomechanics. Upcoming
new features will include hyperelastic shell elements, enhanced strain
tetrahedral elements, a framework for representing mixtures with any
number of charged or uncharged solutes, and dedicated forums for user
support and discussion. We would be happy to add new constitutive models
to FEBio to support your needs. Because of the modular nature of the C++
code, this is an easy task. Finally, if you are interested in helping
with the development of FEBio, please contact me about our Developer’s

If you have any specific questions about FEBio that are not answered in
the manuals, or encounter any problems with download, installation or
use, please feel free to contact us and we will do our best to help you
out. My contact information is available at our lab web page.

I am in debt to our lead code developer, Steve Maas, for his outstanding
work on this project over the past year, and to our web page developer
Wendy Johnson for designing and implementing the web pages for download
site and the database back-end (www.wasatchwebservices.com).
