Energy Incr Convergence Test
The Energy Incr test checks convergence based on the energy increment in the system.
Description
This test is particularly suitable for:
Nonlinear problems with significant energy changes
Problems with material and geometric nonlinearity
Cases where both force and displacement convergence are important
Dynamic analysis
The test calculates the energy increment and compares it to a specified tolerance.
