Default about the nonconservative equation and FVM

Hi,everybody. 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

FVM is commonly applied for problem written in a conservative form. 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.

thanks a lot!!I'll have a try1!! does that mean I can't use the FVM if there are some nonconservative terms only in the source term?

Provided they are written in integral form the FVM can be applied to any system of equations (whether it's a good idea to use the FVM is another matter).
