The open-source FEBio software is written in C++, with particular attention to scalar and parallel performance on modern computer architectures. FEBio offers modeling scenarios, constitutive models, and boundary conditions, which are relevant to numerous applications in biomechanics. This paper provides an overview of the theoretical basis of FEBio and its main features. To address these issues, we developed the FEBio software suite (), a nonlinear implicit finite element (FE) framework, designed specifically for analysis in computational solid biomechanics. This lack of a tailored software environment has hampered research progress, as well as dissemination of models and results. In the field of computational biomechanics, investigators have primarily used commercial software that is neither geared toward biological applications nor sufficiently flexible to follow the latest developments in the field. Maas, Steve A Ellis, Benjamin J Ateshian, Gerard A Weiss, Jeffrey A The authors will present the process of developing these kinds of finite element models,more » using human hand and knee examples, and will demonstrate their software tools.« less Today, we have the resources to model fully three-dimensional, nonlinear, multi-tissue, and even multi-joint systems. In the past, finite element analyses in biomechanics have often been limited to two-dimensional approaches, linear analyses, or simulations of single tissue types. Until recently, tools with sufficient power did not exist or were not accessible to adequately model complicated, three-dimensional, nonlinear biomechanical systems. Ashby, E.įinite element analysis is becoming an increasingly important part of biomechanics and orthopedic research, as computational resources become more powerful, and data handling algorithms become more sophisticated. 3-d finite element model development for biomechanics: a software demonstrationĭOE Office of Scientific and Technical Information (OSTI.GOV)
