Relative Total Energy Incr Convergence Test
The Relative Total Energy Incr test checks convergence based on the ratio of the energy increment to the total energy accumulated in the system.
Description
This test is particularly suitable for:
Nonlinear problems with cumulative energy changes
Cases where total energy history is important
Problems with both material and geometric nonlinearity
Dynamic analysis with energy conservation
The test calculates the ratio of the energy increment to the total accumulated energy and compares it to a specified tolerance.
