The ground reaction forces are +predicted using the GRF prediction algorithm. + + +```{admonition} **Main file Example:** +:class: seealso +{menuselection}`Application --> MocapExamples --> BVH_BoxLift --> Subjects --> S01 --> +S01_T01 --> Main.any` +``` + +The model works using virtual markers placed on the BVH rig (i.e. the stick-figure model +specified by the BVH file). The virtual markers are used to make the Musculoskeletal model +moved similar to marker based MoCap models. + +AnyBody automatically calculates the virtual markers positions, and the model is scaled +directly from the size of the BVH stick figure. Hence the model contains no *Parameter +identification* step to find the parameters. The remaining parts of the model are equivalent to other +{ref}`MoCap model <anymocap>` based on C3D files. + +This particular example shows how to model a box which connects to the hand segments. +This is useful when investigation the effects of interaction with environment objects +even when there is no kinematic data for that object.
