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 but it is not considered Open-source software because it is only free for non-commercial use. 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 [https://febio.org/]). OverviewA brief overview of the available features (as of version 2.8) follows. A more complete list can be found in the FEBio User's manual.
PreView and PostViewFEBio is a command-line application that only implements the solver and analysis algorithms. To assist with setting up FEBio models and analyzing the results, the PreView and PostView programs were developed. PreViewPreView is a finite-element preprocessor that was specifically designed for setting up FEBio models using a graphical interface. It provides functionality for importing or generating 3D meshes, applying material parameters, setting up boundary, loading, and contact conditions, and defining analysis settings. Models are then exported to the xml-formatted FEBio input file. PostViewPostView is a finite-element postprocessor that was designed for visualizing and analyzing the results from FEBio. FEBio stores results in the XPLT format, which can be imported in to PostView. PostView offers many visualizing tools such as contour plots, vector plots, plane cuts, isosurface and slice plots, streamlines and particle flows for flow visualization, and more. Users can take screenshots or record animations. Data can also be filtered and exported in various formats for further processing. SupportSupport for FEBio comes in various forms. A Theory manual and User manual are provided as part of the installation and are available online as well. [https://febio.org/] Users can also ask questions on the FEBio User forums , as well as report bugs and make new feature requests.
