Basically whenever a step is not converged, whether it's passed the maximum number of iterations or the Belos solver fails to converge, the load step is cut in half until convergence. A verification test case is added including all the parameters controlled by the user. - Maximum load step reductions in one step - Maximum total load step reductions After any of these maximum allowable reductions is hit, then either the run is terminated or a switch to the Verlet solver occurs (user controls). - Reduce all remaining load steps If true, after one load-step is reduced, all the remaining steps are reduced too. - Adaptive output frequency If true, after reducing the step size in half, the output frequency is doubled up. - Switch to Verlet -- "Safety Factor" or "Fixed dt" to be set by the user. Otherwise, a safety factor of 0.8 is used. -- "Output Frequency" can be changed at the switch.

Basically whenever a step is not converged, whether it's passed the
maximum number of iterations or the Belos solver fails to converge, the
load step is cut in half until convergence.
A verification test case is added including all the parameters
controlled by the user.
Maximum load step reductions in one step
Maximum total load step reductions
After any of these maximum allowable reductions is hit, then either the
run is terminated or a switch to the Verlet solver occurs (user
controls).
Reduce all remaining load steps
If true, after one load-step is reduced, all the remaining steps are
reduced too.
Adaptive output frequency
If true, after reducing the step size in half, the output frequency is
doubled up.
Switch to Verlet
-- "Safety Factor" or "Fixed dt" to be set by the user. Otherwise,
a safety factor of 0.8 is used.
-- "Output Frequency" can be changed at the switch.
