# Solution Strategy Commands

The solution strategy of a problem is specified by the commands in this section.

Either use the AUTO_SOLUTION_STRATEGY command which issues all the other commands in this section or use those commands individually. If the AUTO_SOLUTION_STRATEGY command is not used then the TIME_SEQUENCE and STAGGER commands must be explicitly given in an input file. All others are optional; if they are not given, their default values are used. Explanations of the relationships between these commands and the overall time stepping and nonlinear iterative strategies are given in the TIME_SEQUENCE command.
