FDM derived from FVM
I have a question concerning Finite Volume Methods.
Many papers, which I have seen describe finite volume techniques like finite differences. For instance:
d(Q*V)/dt + d(F)/dx = 0
Once, I was told that it is possible to derive a quasi-finite difference method from the integral formulation of the conservation laws. I have found a dissertation from Cheong which describes it briefly. What I understood is:
V*dQ/dt + dV/dt*Q = d(Q*V)/dt, V /= f(t) V*dQ/dt = d(Q*V)/dt
But I cannot see how this will help me for the second integral and the flux F. In that diss, the result is:
I would be really glad to see a paper or something else which describes that mathematical trick in details.
Thanks for your help, in advance.
