Скачать или смотреть The Volume-Of-Fluid (VOF) concept

This video demonstrates how a surface can be implicitly represented via the volume fractions in the mesh cells in a Computational Fluid Dynamics (CFD) simulation. The volume fraction in a cell is the fraction of the cell volume that is filled with the "blue" fluid. As the fluid surface moves across the domain initially empty cells are filled up through the faces they share with the neighbouring cells. The "game of VOF" is about efficiently and accurately predicting the amount of blue fluid that is poured from one cell to its neighbouring cells within a small time step.
