In this paper, we report the proposal and development of the numerical model. The model applies to two and three dimensional problems. We introduce the model to the MPS method which is a kind of particle method, and discuss applicability of the model on numerical test of aerial physical pendulum in free torque load; the present model was compared with the theoretical solution by the 4th order Runge-Kutta method. As a result, we confirmed the good reproducibility of the model. And we can say that the model is suitable for analyzing the problem of physical pendulum.
Secondary, we examine the practicability of this model in the regular wave from the calculation results. The tests are examined by a two-dimensional problem in order to reduce calculation cost. In addition, we conducted fluid-structure interaction analysis using the present model and confirmed the applicability of its model to fluid field analysis.
