The Finite Volume Method (FVM) is one of the widely used numerical techniques in the scientific community and in industry as well. In this approach, the partial differential equations that represent the conservation laws to simulate uid flow, heat transfer, and other related physical phenomena, are transformed over differential volumes into discrete algebraic equations over nite volumes (or elements or cells). Thereafter, the system of algebraic equations is solved to compute the values of the dependent variable for each of the elements to represent the physical processes. (from nptel.ac.in)
