Abstract
Interactive simulation technique is incorporated in SPH method which is one of computer simulation methods in modeling and calculating fluid flow by using particles. It is required in the interactive simulation, a simulated object is operated in real-time by equipments of graphical output and controlling device. In the present study, a prototype of simulation program is implemented using “OpenGL” graphics library with perspective for versatile environment of execution. A model of tub charged with liquid (water) and rectangle solid body, which is composed of 301 SPH particles, is investigated in two dimension. It is found that the motion of fluid is induced by the artificial movement of the solid body and a complicated free-surface structure is developed. It is concluded that interactivity facilitate our recognition of phenomena being reproduced in SPH simulation though there remains improvement regarding interactive device and graphical computer resources.
