# (1) int, unique solver tag

Remarks

  1. The modified Newton method only assembles tangent stiffness at the beginning of each sub-step. Automatic stepping can be enabled to obtain optimised computational workload.
  2. The Aitken acceleration is automatically enabled in the modified Newton method.
