Norm Disp Incr Convergence Test

The Norm Disp Incr test checks convergence based on the norm of the displacement increment vector.

Description

This test is particularly suitable for:

Linear and nonlinear static analysis
Problems where displacement convergence is critical
Cases where force equilibrium is less important
Problems with well-defined displacement patterns

The test calculates the norm of the displacement increment vector and compares it to a specified tolerance.

Parameters

Parameter	Type	Description
`tol`	float	Tolerance for convergence (default: 1.0e-6)
`maxIter`	int	Maximum number of iterations (default: 10)
`printFlag`	int	Print flag for convergence information (default: 0)
`normType`	int	Norm type to use: 0 for max-norm, 1 for 1-norm, 2 for 2-norm (default: 2)
