# MacNeal–Harder straight cantilever, regular hex8 mesh with incompatible modes

Our model of the published problem: a beam 6.0 long, 0.2 wide, 0.1 deep (E = 10⁷, ν = 0.3) of the
prescribed 6 × 1 regular elements, here hex8 with incompatible modes, clamped at one end; unit
forces at the free end along the beam, across its width and across its depth (spread over the end
face by area), and a unit twisting moment through a distributing coupling, each a separate step.
Displacements are read at a corner of the free end.
