Claim One:
1. A method comprising: determining a group of subjects fitting a demographic profile for whom a product is to be designed; determining at least one of a set of demographic factors representative of the group of subjects; determining a set of tests based on the at least one of the set of demographic factors, the set of tests facilitating simulations of subjects in the group of subjects using the product; conducting the determined set of tests, the determined set of tests including a set of force data for a set of ergonomic tests under a corresponding set of test conditions performed by multiple subjects; adjusting, by a computer system, a number of muscle parameters for a number of muscles in a musculoskeletal model to adapt to the demographic profile, wherein adjusting the number of muscle parameters comprises: generating a set of force reports corresponding to the set of ergonomic tests by performing simulations with the musculoskeletal model based on the set of force data for the set of ergonomic tests; computing a set of final adjustments using the set of force reports, wherein the set of final adjustments is established by selecting a greatest maximum force limit across the set of force reports for each of the number of muscles; and modifying the musculoskeletal model using the set of final adjustments to generate a tuned musculoskeletal model that is adapted to the demographic profile; performing, by the computer system, biomechanical simulations with the tuned musculoskeletal model to generate information for use in designing the product; and generating, using the information generated by the biomechanical simulations, a design of the product adapted to subjects that fit the profile.
