NOTES

The parameters described in this section are required to run the analysis phase. Many other parameters can be used to control the analysis phase and are defined by the step control parameters. The overall structure of the time stepping procedure is as follows.
 Begin loop over time steps
 Read new step control parameters as controlled by n_{reuse}
 Begin loop over iterations
 The iteration loop is controlled by the step control parameters
 End loop over iterations
 End loop over time steps

During the time stepping procedure, a maximum number of time steps max_{step} will be performed in the loop over the time steps.

The simulation time range is defined by a starting time t_{ini}, and a final time t_{fin}. The simulation will stop when the final time is reached.

If the time step size adaptivity procedure is used, the time step size will vary during the simulation in order to meet a preset level of error, or because some specific event is taking place, such as contact. However, the time step size will not be allowed to be outside the time step size range defined by Δt_{min} ≤ Δt ≤ Δt_{max}.

The reference energy level E_{ref} is used to normalize convergence indices and error norms based on energy.
