In the finite-volume method the problem of estimating partial derivatives (finite differences) is replaced by the requirement to accurately calculate fluxes across cell boundaries.
A finite volume method is based on subdividing the spatial domain into intervals (known as the finite volumes or grid cells) and keeping track of an approximation to the integral of q over each of these volumes.
The finite volume method has often be thought of as a kind of mixed finite element method, since both methods involve the fluxes. However, we show here that, on the simple Dirichlet problem (5.1), the two methods yield two different schemes.
