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.
