Problem
- Unit square $[0,1]^2$, hyperelastic continuum (matyp 1)
- Structured quad4 mesh: 81 nodes · 64 elements
- Roller BCs: left/top $U_X=0$, bottom/right $U_Y=0$; opposite corners pinned
- Initial velocity field → free “swinging” vibration to $t_{\max}=5$
Viewer notes
- Displacements are small ($\sim 10^{-3}$); default scale is $400\times$
- Frames from restart files every 10 increments ($\Delta t = 0.0125$)
- Energy plot from final restart total / kinetic series
