In SIMM, a musculoskeletal model consists of representations of bones, muscles, ligaments, and other structures.
Muscles span the joints and develop force, thus generating moments about the joints.
SIMM enables an analysis of a musculoskeletal model by calculating the joint moments that each muscle can generate at any body position. By manipulating a model using the graphical interface, the customer can quickly explore the effects of changing musculoskeletal geometry and other model parameters on the muscle forces and joint moments. Features Muscle Wrapping. You can interactively define spheres, ellipsoids, and cylinders for muscle-tendon actuators to wrap over. SIMM automatically calculates muscle paths over these wrapping objects.
