The objective of this study was to extend the swimming human simulation model SWUM, which has been developed by the authors, to multi agent/object simulation. By this extension, SWUM can analyze the multiple bodies, that is, the other swimmers and equipments such as fins, starting block, pool wall, and so on. In this paper, the method of extension and its implementation to the software are firstly described. Two examples of analyses are next shown. The first example is simple synchronized swimming by three swimmers. In this simulation, virtual springs and dampers were employed to represent hand connections among the swimmers. Another example is the monofin swimming. In this simulation, the monofin was modeled as a series of five rigid plates. The virtual springs and dampers to represent the connection of the plates were employed. In addition, in order to represent the elasticity of the monofin, rotational springs and dampers among the plates were also employed. The reasonable results obtained in these simulation indicate the validity and usefulness of the present extension.
