Finite Volume Method

A conservative discretization technique that integrates governing differential equations over small control volumes and enforces balance of fluxes across volume interfaces to obtain discrete update formulas.

A numerical discretization method that divides the domain into control volumes and enforces integral conservation of governing equations over each control volume by balancing fluxes across faces; widely used for fluid flow, transport and heat transfer because it preserves conservation at the discrete level and is applicable on structured and unstructured meshes.
