FE2M_Resources

We implemented a 3-D mutiscale framework within FEBio (Version 4.2, University of Utah) combining mixture theory and the FE2-method (i.e. finite elements of multiscale mixtures or FE2M) to solve two-scale, non-linear, coupled, and time dependent boundary value problems (BVPs) for poro-hyperelastic, fluid-saturated porous media.

We attached a representative volume element (RVE) of the microstructure at each material point of the macrostructure and performed discretizations of the BVPs on both macro- and micro-scales. We provide free, public access to our FE2M framework as a plugin for FEBio, including this short user manual and input files for simple test cases.

FEBio is a nonlinear finite element (FE) solver that is specifically designed for biomechanical applications. It offers modeling scenarios, constitutive models and boundary conditions that are relevant to many research areas in biomechanics. All features can be used together seamlessly, giving the user a powerful tool for solving 3D problems in computational biomechanics. The software is open-source, and pre-compiled executables for Windows, OS-X and Linux platforms are available.

Executables for FEBio can be downloaded from https://febio.org/febio/febio-downloads/. Please inform us of publications that use FEBio in research. Information can be found on the Publications tab.
