If the equations(such as the Euler equation or N-S equations) are written in nonconservative form,can it be discretized with the Finite Volume Method,or does it must be solved with Finite Difference Method? And how to deal with it when there are some nonconservative terms in the source term. I used to be deal with the conservative equations with FVM,So I am confused when dealing with the nonconservative equation. I'll be thankful to any reponse. Maximus

In this way, the method will satisfy the total conservation of the fluxes independent of the accuracy of the results. If you have your problem in nonconservative form you can apply FDM without problem. Using the correct number of points you will get the wanted solution.
