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 volume… dwg trueconvert工具WebFirst we have presented an arbitrary high-order Finite Volume scheme based on convex combi-nations of the standard ﬁrst-order Godunov scheme and on a separated treatment of the space and time discretizations.
