ENERGY BALANCE VERDICT¶
Adjudicate an LS-DYNA run’s global energy balance: 6 advisory metrics (hourglass/IE, eroded-KE/KE, eroded-IE/IE, total-energy drift, sliding-interface contact energy [negative = unambiguous failure], added-mass %) -> PASS/FLAG verdict. Input is the glstat energy curves (from a binout_user_extractor run); thresholds are advisory rules of thumb, not absolute acceptance gates.
When to use¶
Tagged: energy, balance, glstat, hourglass, erosion, contact, added_mass, verdict.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| glstat Curves (JSON) | curves | text | — | ✓ | JSON array of {“component”: name, “points”: {“y”: […]}} – the binout_output.curves from a glstat binout_user_extractor run with components total_energy, internal_energy, kinetic_energy, hourglass_energy, eroded_kinetic_energy, eroded_internal_energy, sliding_interface_energy, added_mass, energy_ratio, percent_increase. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Energy Balance Verdict | verdict_result | keyvalue | Assoc: verdict (PASS/FLAG/ERROR), flag_count, metrics_with_insufficient_data, metrics (per-metric value/threshold/pass/note), channels (first/last/n_states), advisory. |
