The solvable condition for the mps simulations was investigated in an enclosed calculation region and the reason for the numerical instability was ****yzed when the mps particles knock at the solid wall or liquid surface is with a relatively large velocity.
分析了mps方法求解封闭区域流动的有解条件、自由面流动中粒子以较大速度撞击壁面或液面时出现的不稳定现象。
