rdf:langString FEBio(Finite Elements for Biomechanics) is a software package for finite element analysis and was specifically designed for applications in biomechanics and bioengineering. It was developed in collaboration with research groups from the University of Utah (MRL, SCI) and Columbia University (MBL). FEBio offers modeling scenarios, constitutive models, and boundary conditions that are relevant to numerous research areas and specializes in the analysis of 3D multiphysics models that can undergo large deformations. Users can solve problems in solid mechanics, contact analysis, porous media problems, fluid mechanics, and as of version 2.8, fluid-solid interaction (FSI) problems as well. FEBio supports both quasi-static and dynamic analyses. A more detailed overview of FEBio's features follows below. The source code for FEBio is publicly available and, as of version 2.9, distributed under the MIT License. Older versions are available under a custom license and are not considered Open-source software because they are only free for non-commercial use. The source code is available on GitHub ([1]) FEBio supports a plugin framework that allows users to easily extend and customize the set of features for their specific needs. Using this plugin framework users can develop new constitutive models, boundary conditions, body loads, nonlinear constraints, and even new finite element solvers (see e.g. the FEBioChem plugin, which implements a reaction-diffusion solver for solving chemical reactions in mixtures [2]).
