Load: Traction on the face \(\mathrm{[}\mathrm{3,}\mathrm{4,}\mathrm{8,}\mathrm{7,}\mathrm{11,}\mathrm{16,}\mathrm{19,}15\mathrm{]}\)

The total number of increments is 20 (20 increments between \(t\mathrm{=}\mathrm{0s}\) and \(\mathrm{2s}\))

Convergence is achieved if residue RESI_GLOB_RELA is less than or equal to 10—6.
