Swimming Human Simulation Software "Swumsuit"

Last update : 2014/7/15


What is Swumsuit?

Swumsuit (SWimming hUman Model with Synthetic User Interface Tools) is a software on which the swimming human simulation model SWUM is implemented. Data for body geometry, joint motion and analysis settings are given to "analysis engine" part as input. The analysis engine estimates the fluid force acting on the human body from the given input data, solves the equations of motion of the human body as a rigid body, and compute the abosolute motion of the human body. The analysis engine also outputs many data, such as swimming speed, propulsive efficiency, thrust, joint torque and so on, obtained by the analysis.

By using Swumsuit, the user can perform all tasks during the analysis with easy GUI (Graphical User Interface) operation, such as editing input data, starting analysis, displaying many quantities of the results with graphs and animation, without being conscious of inside the difficult simulation program.

Due to this advantage, Swumsuit enables everyone to perform simulation of the human swimming, which has been thought to be difficult because of complicated formulation for body motion and fluid force.

Swumsuit is a Free Software distributed under GPL (Gnu General Public License).

By Whom?

Swumsuit is developed by developing team lead by Prof. Motomu Nakashima, Tokyo Institute of Technology, Japan.
