COMPUTE LUCY MPDB MEASUREMENTS¶
Computes LUCY MPDB (Mobile Progressive Deformable Barrier) measurements from an LS-DYNA d3plot result file. Extracts geometry-based KPIs — such as cladding/backplate deformation and barrier interaction distances — in a specified velocity direction, and returns a structured measurement view for post-processing and reporting.
When to use¶

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| D3plot Name | d3plot name | string | — | Path or filename of the LS-DYNA d3plot binary results file to read; this is the primary simulation output from which all measurements are extracted. | |
| Cladding Part | cladding_part | text | — | Part ID (PID) of the MPDB cladding component; used to measure cladding deformation and surface interaction with the barrier. | |
| Backplate Part | backplate_part | text | — | Part ID (PID) of the MPDB backplate component; used to track backplate displacement and compute ODB/intrusion metrics. | |
| Barrier Parts | barrier_parts | text | — | One or more part IDs (PIDs) representing the deformable barrier structure (comma-separated, e.g. PID1, PID2); all listed parts are included in barrier-side measurement calculations. | |
| Velocity Direction | velocity_direction | string | 1 0 0 | Unit vector defining the primary impact/velocity direction as three space-separated values (e.g. ‘1 0 0’ for positive X); defaults to ‘1 0 0’ — change only when the impact axis in the model differs from the global X-axis. | |
| Max Dist | max_dist | text | — | Optional maximum search distance (in model length units, e.g. mm) used to filter or cap measurement computations; leave blank to apply no distance limit. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| lucy_mpdb_measurements_output_1 | lucy_mpdb_measurements_output_1 | view | Structured view containing all computed LUCY MPDB measurements (deformation depths, barrier interaction metrics, and KPI values) extracted from the d3plot for downstream reporting or post-processing. |
