• Resumen

  • These notes rebut some overreaching conclusions of Svärd et al., 2008 [19] concerning relations between truncation and discretization errors on irregular grids. Convergence of truncation errors severely degrades on general irregular grids. Such degradation does not necessarily imply a less than design-order convergence of discretization errors.
