The Z-section cantilever under an end torque as five hex20 blocks (two flanges, two corner blocks, the web; two elements through every wall): axial stress at A, on the mid-surface of the lower flange at its free edge, -109.45 against -108 (2%). The solid model converges to about -109.7, 1.6% beyond the thin-walled reference, as ESRD's converged p-version solid (-109.5) does. The README also records the MITC4 mid-surface shell model of the same problem, which converges to about -111.3 (3.1%), and why the case is the solid. Part of #97.
