Abstract This work introduces a modelling framework towards a forward dynamics simulation of skeletal muscle mechanics that couples three‐dimensional (3D) continuum‐mechanical‐based Finite Element (FE) simulations to rigid body simulations. In this regard, this is a methodological approach, which incorporates different methods to realise simulations of the musculoskeletal system. Such simulations are at present computationally not feasible. To set up such a modelling framework the upper limp is selected. Here, the upper limb consists of an antagonistic muscle pair, the elbow (a simple hinge joint) and an external load. The skeletal muscles are represented by a 3D continuum‐mechanical model. The tendons are, for now, assumed to be rigid. The results demonstrate the ability of the system to converge to a physiological realistic position. (© 2012 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
