As always, we would really appreciate any feedback that you may have to help us improve FEBio.Post LASIK ectasia is defined as a reduction in biomechanical integrity to below the threshold required to maintain corneal shape and curvature. We also would like to take this opportunity to thank our ever-growing user base for helping us make FEBio a great tool for computational biomechanics.

#Febio postview software#

We encourage you to report any problems or questions on the Software Forum: These packages can also be downloaded from. įEBio's supporting software, PreView and PostView, have also undergone some major improvements, making it easier than ever to create, define and analyze finite element models with FEBio.

These can be useful for developers who want to know which files in the source code were effected by particular changes. The svn logs have been added to the Help directory of the download. The release notes have been updated and can also be downloaded separately from the Documentation tab of the software page. When a nodal degree of freedom is specified to be relative at a particular step, the value prescribed for that node is superposed over the value of that degree of freedom at the end of the preceding step.Īll documentation has been updated and can be downloaded from. Relative boundary conditions are meaningful only in multi-step analyses. Relative boundary conditions have been implemented for all nodal degrees of freedom of displacement, fluid pressure, and solute concentration. A cell growth material has been implemented, which describes the growth of cells as driven by osmotic forces, due to the increasing (or decreasing) content of intracellular solid and membrane-impermeant solute. Electric potential and current density are evaluated in all triphasic analyses. The solid matrix may carry an electric charge (the fixed-charge density), in which case the triphasic material will undergo swelling due to Donnan osmotic pressure. A triphasic material consists of a solid, a solvent, and two solute species that are monovalent counter-ions. Triphasic materials have been implemented in this version. For biphasic-solute materials, backward compatibility is maintained with the FEBio 1.4 file format, though only one solute may be used throughout an analysis in the old format. Each region that contains solutes must provide the solute id's corresponding to the entries in the solute table. A solute table must now be provided in the input file, which lists all the solutes appearing in a particular analysis. For example, adjacent regions of biphasic-solute materials need not have the same solute. FEBio has been updated to allow different solutes to be used in different regions of a model. Some of the noteworthy changes and additions are listed below. This new version includes some major changes and contains a number of new and exciting features. FEBio is an open-source finite element package, specifically designed for solving problems in the field of computational biomechanics. We are excited to announce the arrival of version 1.5 of FEBio (Finite Elements for Biomechanics).
