![]() 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 source code is available on GitHub ( )įEBio supports a plugin framework that allows users to easily extend and customize the set of features for their specific needs. 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 for FEBio is publicly available and, as of version 2.9, distributed under the MIT License. ![]() A more detailed overview of FEBio's features follows below. FEBio supports both quasi-static and dynamic analyses. 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. It was developed in collaboration with research groups from the University of Utah (MRL, SCI) and Columbia University (MBL).įEBio 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. I'm not sure if that is enough though, for instance if your motion is so complex that you need negative entries in the load curve I am not sure if that is allowed/valid (is it Steve?) otherwise you would probably need multiple load curves and steps.FEBio (Finite Elements for Biomechanics) is a software package for finite element analysis and was specifically designed for applications in biomechanics and bioengineering. So if you can formulate your desired displacement history as a function of the total displacement for each component then this is possible. smooth or multi-linear) whereby you specify each point on the curve as you wish like would be a different history. To make it vary in time in a more complicated fashion you could either have multiple load curves and steps as suggested before or you could specify a single load curve (e.g. If the load curve is just the linear curve then the variation in time is linear like that for a single step. ![]() Perhaps what you want is to specify your total displacement as a function of a specific load curve. You can also specify nodal displacements for each node or element separately as you which. See here for a MATLAB toolbox that links with FEBio. FEBio Studio 2.1 has been released! This new version contains a lot of bug fixes, but also quite a few new capabilities.The FEBio software downloads and knowledgebase can be found here. ![]() This will allow you to stay up to date on recent activity on the forum. You can subscribe to forums by pressing the "Subscribe" button at the top of the forum. Moderators are here to assist with explaining novel features, addressing bug reports and reviewing feature requests, but the effectiveness of the forum depends critically on the participation of experienced users who can assist novices or share ideas and models that explore challenging problems. A broad level of participation is encouraged, to create a vibrant community that helps improve the quality and usefulness of these open-source/free software products. Forum participants are encouraged to post questions, as well as answer posts from others. This forum serves the community of FEBio and FEBio Studio users and developers.
