Piecewise-Paraboloid Interface Calculation

A numerical method for tracking the interface between two immiscible fluids in computational fluid dynamics simulations. It approximates the interface shape using piecewise parabolic segments to improve accuracy and stability compared to simpler methods like the Volume of Fluid (VOF) method. / 一种用于计算流体动力学模拟中追踪两种不相溶流体之间界面的数值方法。它使用分段抛物线段近似界面形状，以提高相对于VOF（体积分数）方法等更简单方法的准确性和稳定性。
