Automated Cell Scale Meshes

This package provides scripts, meshes, and models utilized in the manuscript "Automated Generation of Tissue-Specific Three-Dimensional Finite Element Meshes Containing Ellipsoidal Cellular Inclusions". The scripts provide the capacity to build meshes of prismatic tissue volumes with spherical and/or ellipsoidal inclusions of cells surrounded with a pericellular matrix. The tool requires Python (http://www.python.org) and Salome v6.3.1 (http://www.salome-platform.org/) to operate. Multiple example meshes, all described in the manuscript, are also provided.

Autonomous Pipeline

This package contains i) macroscopic finite element representation of the tibiofemoral joint, ii) two different microscopic finite element representations of chondrocyte environment (single cell vs 11 cell), iii) simulation results for the macroscopic model, iv) simulations result of microscopic models post-processed by macro level solution. The study is conducted through an autonoumous multiscale analysis pipeline described in publications referred below.

Biphasic Multiscale Analysis

This package contains materials to explore data passing assumptions to conduct cell scale biphasic simulations from the results of biphasic tissue simulations. Four cases of tissue loading and boundary conditions were implemented in tissue scale models (four combinations of uniform/nonuniform displacement and symmetric/asymmetric permeability). Two cases of data passing assumptions were tested to drive cell scale models (first order and second order data passing).

Multiscale data set

This package provides a comprehensive specimen-specific multiscale anatomical and mechanical testing data set for the tibiofemoral joint. For macro and micro scale geometry, magnetic resonance images and histology images are provided respectively. Mechanical testing data at the joint level consists of laxity tests and a combined loading scenario. 12 tissue samples (cartilage, ligaments and menisci) were tested in either compression or tension under stress relaxation conditions to characterize the tissue properties. This data can be useful in developing multi-resolution specimen-specific models of the tibiofemoral joint.

Single vs. Eleven Cell Study

This package provides scripts, meshes, and models utilized in the manuscript "The Potential for Intercellular Mechanical Interaction - Simulations of Single Chondrocyte Versus Anatomically Based Distribution" (currently ahead of print). The scripts provide the capacity to build meshes, run simulations, and process results for models of biphasic, transition zone chondrocyte mechanics for single and anatomically based eleven cell distributions. The tool requires Python (http://www.python.org) and FEBio v1.5.0 (http://febio.org/) to operate.
