Abstract
Generally, wall boundary model in particle method is modeled by using fixed particles. However, high resolution is required from the viewpoint of shape reproducibility when boundary is complicated geometry. On the other hand, the boundary model for a wall expressed by triangle patches utilized for CAD has been often used in MPS based commercial codes. The problem is improved by the approach to some extent in that case. However, there is no useful method to deal with the large deformation of wall boundary. In this research, the wall boundary model which does not use a distance function was developed, and it was applied to the SPH method. Furthermore, it was shown that the fluid behavior in the wall boundary with large deformation as a restriction condition could be calculated. The validity of the proposal calculation method was presented.
