LSDYNA CONTACT TIME HISTORY¶
Extracts full time-history contact force curves from LS-DYNA rcforc (binout) output for a given simulation, then computes per-interval interaction matrices and rich curve statistics (peak force, impulse, max slope, etc.) for every contact part-pair. Use this worker to understand how contact forces evolve across time intervals and which part interactions are most significant.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Simulation | simulation_id | remote_lookup | — | Reference to the LS-DYNA simulation record whose binout and d3hsp files will be read; select from the remote simulation lookup. | |
| Number of Time Intervals | num_intervals | integer | 10 | Number of equal-width time intervals to divide the simulation duration into for the interval matrices (integer 1–100; default 10). | |
| Interval Range | interval_range | string | — | Optional colon-delimited slice of intervals to include in the interval_matrices output (e.g. ‘4:10’ returns intervals 4 through 10 inclusive); leave empty to return all intervals. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Contact Force Profiles | contact_force_profiles | dataset | Dataset of one row per contact, containing contact metadata (name, slave/master part IDs) and full-simulation resultant-force curve statistics (peak force, impulse, max slope, number of time points), sorted by peak force descending. |
| Interval Matrices | interval_matrices | dataset | Dataset of per-interval, per-part-pair interaction rows (filtered to the requested interval_range), each containing interval index, time bounds, and curve statistics computed over that interval window. |
| Summary | summary | string | Human-readable string reporting the number of contacts extracted, interval count, active interval range shown, count of contacts with non-zero peak force, and any range-clamping warnings. |
