time-stepping

separate

Plan and control time-step policies for simulations. Use when coupling CFL/physics limits with adaptive stepping, ramping initial transients, scheduling outputs/checkpoints, or planning restart strategies for long runs.

When to use

• coupling CFL/physics limits with adaptive stepping
• ramping initial transients
• scheduling outputs/checkpoints
• planning restart strategies for long runs
• choosing time steps
• monitoring time steps
• planning output cadence
• planning checkpoint cadence

When not to use

• **Not adaptive control**: Plans static schedules, not runtime adaptation
• **Assumes constant physics**: If parameters change, re-plan
