水泳人体シミュレーションソフトウェアSwumsuitの開発  [in Japanese] Development of the Swimming Human Simulation Software "Swumsuit"  [in Japanese]

This paper describes the swimming human simulation software "Swumsuit", which was developed by the authors in order to analyze mechanical problems in human swimming. Swumsuit is an implementation of the swimming human simulation model "SWUM", which has been developed by the authors and whose validity has been already verified. Swumsuit is a free software under GPL, and consists of the analysis engine part written in Fortran and GUI part written in Tcl/Tk. In this paper, the summary of SWUM is firstly described. Next, Swumsuit's structure, specification, and the function of each part, that is, startup window, editor for body geometry, joint motion and analysis settings, animation display part, and graph display part, are respectively described in order to show its practicality. In addition, analysis examples and its applications in various areas are demonstrated in order to show its usefulness.
