pc Guest Posts: n/a	Does anyone have experience with applying Richardson extrapolation to compute estimated errors for the whole flowfield? I'm not referring to globally integrated quantities such as lift/drag, put pointwise application of Richardson extrapolation at each (x,y,z) on the finest grid. One must have solution data at the same (x,y,z) from each of the meshes used, so some interpolation is required. However I haven't seen this detail described well in various papers. Many don't mention it at all. Any comments? Thanks.
