We tried to convert our muscles from Schutte model to the Millard model by copying in the appropriate muscle parameters. When we opened our models in OpenSim and checked the forces, they were extremely low. For example, one muscle with a maximum isometric force of approximately 170 N (and is close t...

Our goal is to perform a joint reaction analysis of the Vasavada Neck Model that was originally developed in SIMM. We are having trouble doing this and would be grateful for any insight that can be provided. When using the 'Import SIMM Model' tool in OpenSim 3.3, the muscles from the .msl file are a...
