Gadget Simulation Blueprint

Define the use case

• Decide whether the run is collisionless, hydro, or fully coupled.
• List the primary scientific metrics and required output products.
• Translate target physical scales into particle counts and softening lengths.

Numerical setup

• Choose gravity and time-integration tolerances for your target accuracy.
• Set SPH-related parameters and run at least one sensitivity test.
• Include a small-box pilot to check throughput and stability.

Data and analysis plan

• Set snapshot cadence based on expected dynamical timescales.
• Keep lightweight monitoring channels running at higher frequency for QA.
• Reserve storage for restart files and total expected data volume.
