MOTION ANALYSIS METHOD, MOTION ANALYSIS SIMULATOR AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a motion analysis method, a motion analysis simulator and a program, which simplify motion analysis, and enables to accurately perform motion analysis of motion of a body in passive fluid and even motion of a body in active fluid. PSOLUTION: The motion analysis method performs, at each predetermined time step, a fluid analysis step s1 for calculating pressure of each element constituting a model of a body in fluid by numerical fluid dynamics, and a motion analysis step s2 for obtaining fluid force by the pressure to calculate at least the position and attitude of the model by a motion equation of a rigid body system. The motion analysis simulator includes a fluid analysis unit 1 for calculating pressure of each element constituting a model of a body in fluid by numerical fluid dynamics, and a motion analysis unit 2 for obtaining fluid force from the pressure to calculate at least the position and attitude of the model by the motion equation of the rigid body system.
