Nettet29. nov. 2024 · So far, there is no difference between the finite element and finite volume methods. As we can see above, the formulation for finite volume methods, Eq. 16, is just a special case of the generic weak formulation used in finite element methods, Eq. 15. The difference is found in the discretization of Eq. 15 and Eq. to reach you by phoneNettetA finite difference scheme is stable if the errors made at one time step of the calculation do not cause the errors to be magnified as the computations are continued.
