finite volume method

The finite volume method is a numerical technique used to simulate physical systems, especially those involving fluid flow or heat transfer. It divides the entire system into small, manageable regions called volumes. By applying the basic principles of conservation (like mass, momentum, or energy) to each volume, it ensures that what flows in minus what flows out equals the change within. The method then calculates approximate solutions for each small volume, which together provide an overall picture of how the system behaves. This approach is widely used in engineering to accurately predict complex physical phenomena.
