Hi again,
I have examined my mesh (which you can find in the attachment) with Salome and
gmsh – there are no flat faces at the boundaries. But there are line elements!

Hi Kenneth,
thank you for the quick answer!
So it seems not that trivia

Matthias,
The gradient is estimated with finite differences. Thus, it is not wholly
unexpected that there could be differences at the boundaries. However, the
algorithm does not assume zero for adjacent cells at the boundaries.

Hi,
when I use the gradient filter (unstructured dataset), I observe edge effects
which are IMO unphysical. For the nodes on the outer boundary of my domain, the
gradient magnitude is smaller than I would expect. The behavior is like the
filter tries to use the adjacent nodes to calculate the
