NonLinear.nr_parameters

Parameters to set the newton raphson algorithm: * ‘err0’: The reference error.

Default is None (automatically computed)

• ‘criterion’: Type of convergence test in [‘Displacement’, ‘Force’, ‘Work’]. Default is ‘Displacement’.

• ‘tol’: Error tolerance for convergence. Default is 1e-3.

• ‘max_subiter’: Number of nr iteration before returning a convergence error. Default is 5.

• ‘norm_type’: define the norm used to test the criterion Use numpy.inf for the max value. Default is 2.
