Within the European economy, digital modelling activities and especially simulation of human motion have emerged during the last decades. The ability to realistically predict real-world observations is key to remain competitive. In order to introduce approaches and software solutions, which are capable to automatically simulating a rich repertoire of realistic human motions, MOSIM aims to develop and implement a generic concept, inspired by the FMI standard, transferring the idea of co-simulating models from different simulation environments to the field of human simulation by introducing the Motion Model Units.
