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
0.00

By patch vertices you mean the nodes of each element, hence
DataPostprocessor gives me the gradients with respect to the mapped gauss
points to the nodes

Hi,
Using the postprocessor approach according to step-33 I have computed the
strain tensor successfully by means of the
Postprocessor::compute_derived_quantities_vector function and its
displacement gradient duh.
Unfortunately, within an arbitrary function called right after I solve the
