Supplementary data, models, and code for "Scaling contact force parameters across body size, limb count, and number of contact spheres"

This dataset contains OpenSim models and simulation code (Matlab) that generates all the figures and data from PA van Bijlert (2026) "Scaling contact force parameters across body size, limb count, and number of contact spheres". Journal of Biomechanics. https://doi.org/10.1016/j.jbiomech.2026.113420. The plotting code will analyse the outputs that are already present in the folders, generating the figures from the manuscript. The simulation code will overwrite the existing outputs. OpenSim Moco is not deterministic when using different machines (due to IPOPT's parallelisation), so rerunning the simulations will overwrite the existing outputs and may give slightly different results. The models are modified from different publications (except for the giraffe, which is new). Please cite the original publications if reusing them. These are listed in the model subdirectories, and also in the paper that this dataset is supplementary to.
