This talk will discuss a third-order edge-based finite-volume scheme on unstructured grids. It will be shown why the edge-based scheme can be third-order and also why it cannot be third-order if the numerical flux is exact for quadratic fluxes. A general boundary flux quadrature formula is presented that preserves third-order accuracy at boundary nodes with linear elements. Numerical results show that the general formula as well as acccurate boundary normals are essential to achieve third-order accuracy for a curved boundary problem with linear elements.
