Target Outcome

Finite element mesh of the full knee OR compartments of interest, e.g. cruciate complex, patellofemoral joint, ready for model development:



  • Python. Python is a programming language (GPL compatible license, Python is the default scripting environment for Open Knee(s); for more details, please refer to Infrastructure/ScriptingEnvironment.

  • SciPy. SciPy is a Python based open-source software for mathematics, science, and engineering (BSD license, see

  • Spyder. Spyder is an interactive development environment for Python with advanced editing, interactive testing, debugging and introspection features (MIT license, see

  • npTDMS. npTDMS is Cross-platform, NumPy based module for reading TDMS files produced by LabVIEW. TDMS files are the binary files used for the robotic testing raw data. (LGPL license, see

Previous Protocols

For more details, see Specifications/MeshGeneration.



Finite element mesh of ALL tissues of interest (within the compartment or in the whole knee); in human readable format, e.g., Abaqus input (INP) file, XML file, or as open format binary files, e.g., MED file, including


Scripted Procedure for Mesh Assembly

This python script will read the xml file with the connectivity of several med files in the same coordinate system including groups of nodes, elements, faces, etc. It will then create an FEBio model file (.feb, version 2.5) containing all the groups, and the ties/contacts as specified in the Connectivity File.

The directions for running the script from Salome are identical to those for running the script, as described in Specifications/MeshGeneration. The script uses the same connectivity file as well.
