Examples of variables that can be optimized are: * The ''max_isometric_force'' of a muscle * Location offset or radius of contact geometry * Stiffness and damping of a ''CoordinateLimitForce'' Properties can be set either directly, via an ''offset'', or by multiplying them by a specific ''factor''. Values can be defined via a special ''Properties'' section inside the ''OpenSimModel'' section: <code> OpenSimModel { model_file = data/Human0914.osim Properties { # increase left iliopsoas force by factor 2 iliopsoas_l { max_isometric_force.factor = 2 } # optimize y position of contact geometry and reuse parameter for left side r_toe { location.offset { x = 0.02~0.01<-1,1> y = 0 z = 0 } } l_toe { location.offset { x = r_toe.location.offset.x y = -0.005 z = 0 } } # optimize knee limit stiffness and damping and reuse parameters for left side KneeLimit_r { upper_stiffness = 1~0.01<0.1,5> damping = 0.1~0.01<0.01,1> } KneeLimit_l { upper_stiffness = KneeLimit_r.upper_stiffness damping = KneeLimit_r.damping } } } </code>
