ReadySim aims to provide a means for researchers to perform musculoskeletal simulations directly in a finite element framework. Both the framework and the models are made open source to improve the dissemination of knowledge and drive continuous improvements to model design and modeling techniques.

The software uses MATLAB and Python to interface with ABAQUS/Explicit input and output files and includes modules for model segment scaling, kinematics estimation, and muscle force optimization. The JobQueue API allows for asynchronous process control via MATLAB to parallelize optimization problems and improve computational runtime when possible.
