Finite volume method for 1D heat equation in 1D
The simple answer is, as I now realise, that you are free to compute the fluxes however you please, and the fluxes are evaluated on the cell boundaries, so I can just insert the actual values for the ...

Adding a diffusion term to the MUSCL - Kurganov and Tadmor central scheme
From a finite volume point of view, fluxes should be calculated at the cell faces and added up for each cell.
However, since you are using Cartesian meshes and your material properties are constant, ...
