Figure 8:

Deformations and y-displacement of the Cook’s membrane benchmark with both elemental and nodal coupling at different points in time. Time values are start of the simulation, (roughly) $0.5T_1$, and $T_{\text{f}}$. In both cases the structures are discretized with ${𝓠}^1$ elements. The nodal case uses $M_{\text{FAC}}=1.0$ and the elemental case uses $M_{\text{FAC}}=2.0$.
