PLIC3D algorithm, a 3-dimensional VOF method with piecewise linear interface construction and split and unsplit propagation, is specially devised for better solution to free surfaces. Particularly split PLIC3D is applied in numerically modeling draining from bottom of a cylindrical vessel and water-exit of a revolution body, from which evolutions of free surfaces are mainly illustrated.

重点在直角坐标系中推导了用斜面构造自由界面，使用分裂和不分裂推进的三维VOF方法：PLIC3D，以改善自由面求解精度；并用分裂的PLIC3D算法模拟了三维的柱形容器泄漏和旋成体出水问题，结果主要显示了它们的液面运动变化。
