Finite Volume Method: A Crash introduction - Wolf Dynamics
Finite Volume Method: A Crash introduction Before continuing, we want to remind you that this a brief introduction to the FVM. Let us use the general transport equation as the starting point to explain the FVM, We want to solve the general transport equation for the transported quantity in a givendomain, with given boundary conditions BC and initial conditions IC. This is a second order equation. For good accuracy, it is necessary that the order of the discretization is equal or higher than the order of the equation that is being discretized.
Finite Volume Method: A Crash introduction Profile assumptions using Taylor expansions around point P (in space) and point t (in time) • Hereafter we are going to assume that the discretization practice is at least second order accurate in space and time. • As consequence of the previous requirement, all dependent variables are assumed
