KW - superconvergence, nonconforming rotated $Q_1$ element, Kershaw mesh.
AB - <p style="text-align: justify;">For the nonconforming rotated $Q_1$ element over a mildly
distorted quadrilateral mesh, we propose a superconvergence property at
the element center, the vertices and the midpoints of four edges.
Numerics are presented to confirm this observation.</p>
