Newton

The Newton solver defines a classic (modified) Newton-Raphson solver.

Syntax

solver Newton (1)
solver modifiedNewton (1)
solver mNewton (1)
# (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.
