I checked the Gauss points within my normal computation using FEValues and compared them with the evaluation points from the DataPostprocessor:
GAUSS POINT COORDINATES 0.211325 0.211325 0.788675 0.211325 0.211325 0.788675 0.788675 0.788675 EVALUATION POINTS 0.000000 0.000000 1.000000 0.000000 0.000000 1.000000 1.000000 1.000000 This means everything we do in DataPostprocessor is evaluated directly in the mapped Gauss points which is actually the reason why we use this postprocessor approach. We want to map the solution of quantities stored on the Gauss points to the physical nodes, so we can visualize them in a proper way. I hope this is correct, because then I assume that both approaches are correct and just differ by a simple mapping procedure. Kind regards, S. A.
