5.5.2. Newton Algorithm¶

algorithm('Newton', secant=False, initial=False, initialThenCurrent=False)

Create a Newton-Raphson algorithm. The Newton-Raphson method is the most widely used and most robust method for solving nonlinear algebraic equations.

 secant (bool) Flag to indicate to use secant stiffness. (optional) initial (bool) Flag to indicate to use initial stiffness.(optional) initialThenCurrent (bool) Flag to indicate to use initial stiffness on first step, then use current stiffness for subsequent steps. (optional)
