We study the implicit upwind finite volume scheme for numerically approximating the advection-diffusion equation with a vector field in the low regularity DiPerna-Lions setting. That is, we are concerned with advecting velocity fields that are spatially Sobolev regular and data that are merely integrable. We prove that on unstructured regular meshes the rate of convergence of approximate solutions generated by the upwind scheme towards the unique solution of the continuous model is at least one…

The numerical solution of second-order boundary value problems on nonuniform meshes
TLDR
It is shown that certain commonly used difference schemes yield second-order accurate solutions despite the fact that their truncation error is of lower order, which illuminates a limitation of the standard stability, consistency proof of convergence for difference schemes defined on nonuniform meshes.
