The finite volume method (FVM) is a method for representing and evaluating partial differential equations in the form of algebraic equations. In the finite volume method, volume integrals in a partial differential equation that contain a divergence term are converted to surface integrals, using the divergence theorem. These terms are then evaluated as fluxes at the surfaces of each finite volume. Because the flux entering a given volume is identical to that leaving the adjacent volum… WebThe equations written for each volume are then assembled, providing a unique algebraic system to be solved using numerical methods. Owing to the similarity with the FDM and … farm credit leasing corporation
