The high-order schemes in MPS method can enhance accuracy but easily suffer from numerical instability at free surfaces. In this study, a new free-surface-detection method based on the stability analysis is proposed to solve this problem. Numerical examples demonstrated that the new method detected fewer free-surface particles but enhanced the stability.
