OpenSim is a specialized Windows application oriented toward professional medics. There are tools for constructing custom skeletal models to analyze the gait and design medical implants. Moreover, surgeons can use OpenSim to plan complex procedures.

Model creation

You are able to import existing 3D objects or generate new models. It is possible to configure custom inverse kinematics and dynamics to better fit the project. Instruments for analyzing the muscle structure and joint reactions are provided as well.

There is a flexible application programming interface for extending the basic functionality of the program and generating personalized simulations. Users can write scripts in MATLAB or Python to access internal libraries and automate complex tasks.

Parameters

The Preferences menu lets you change the default locations for scripts and geometry objects. Additionally, an option to restore previous models on startup is included.

Users can adjust the radii of experimental markers and muscle displays. This functionality is intended for visualizing virtual musculoskeletal structures.

Features

free to download and use;
lets you create and analyze musculoskeletal structure models;
helps physicians plan surgeries and enhance the physical performance of a patient;
supports MATLAB and Python scripts for automating complex simulation tasks;
compatible with all modern versions of Windows.
