PEDESTRIAN PROTECTION EVALUATOR¶
Runs pedestrian protection (PedPro) LS-DYNA simulations by combining a vehicle baseline model (or pre-positioned inputs) with one or more impactor types (headform, lower leg, upper leg) at defined strike positions. Submits a batch of HPC jobs for each position and collects the resulting study and simulation records for downstream post-processing.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Study Name | study_name | text | PedPro Simulations | ✓ | Human-readable label assigned to the PedPro simulation study; defaults to ‘PedPro Simulations’ and is used to group all submitted jobs. |
| Impactor Type | impactor_type | select | headform | Selects the pedestrian impactor type to use — ‘headform’, ‘lower_leg’, or ‘upper_leg’ — which determines the impactor FE model and applicable injury criteria extracted during post-processing. | |
| Vehicle Input Files | main_input_files | file | — | ✓ | Vehicle LS-DYNA input deck(s): upload multiple flat files or a single ZIP archive; if zipped, the main include file must contain the word ‘main’ in its filename. |
| Input file type | input_file_type | select | baseline | Specifies how impactor positions are encoded in the uploaded files: ‘baseline’ (single model with embedded positions), ‘positioned_folders’ (ZIP with one sub-folder per position), or ‘positioned_files’ (individual pre-positioned decks). | |
| Impactor Positions | impactor_positions | dataset | — | Optional dataset supplying impactor strike positions (translations, direction cosines, rotation centre, angle) when ‘baseline’ input_file_type is selected; leave empty if positions are baked into the file structure. | |
| Impactor Position Mapper | impactor_positions_col_map | mapper | — | Column mapper that aligns dataset fields from impactor_positions to the required position schema (X/Y/Z-Translation, X/Y/Z-Cosine, X/Y/Z-Rotation-Center, Angle); must be configured whenever impactor_positions is supplied. | |
| Part and Sensors Map for Post processing | part_and_sensors_map | keyvalue | (complex) | ✓ | Key-value map of LS-DYNA part IDs and sensor/load-cell IDs used during post-processing to extract contact, tracking-node, femur, and tibia responses; defaults cover a standard single-impactor model setup. |
| Impactor Node Set Id | impactor_node_set_id | text | 1 | Impactor node set id | |
| Impactor Transform Id | impactor_transform_id | text | 1 | Impactor transform id | |
| Template ID | template_id | remote_lookup | — | ||
| Project ID | project_id | remote_lookup | — | ||
| Study ID | study_id | remote_lookup | — | ||
| Saved HPC Config | saved_hpc_config | remote_lookup | — | ||
| Run Baseline Only | baseline_only | select | yes | ✓ | Option to run baseline or all positions |
| Impactor Position file pattern | position_file_pattern | text | PedShot | Impactor Position File Name pattern. This file will be replaced | |
| Main input file pattern | main_input_file_pattern | text | Main | Main input file pattern. This file will be used to replace the positioned files | |
| Termination Time | term_time | text | 0 | Optional termination time. Only supported for positioned files | |
| Include Files pattern | include_files_pattern | text | INCLUDE | Include file pattern. Only files matching this pattern will be included in the simulation basides the main and the pedshot file | |
| Update main input file name with Impactor filename | update_main_file | select | no | ✓ | Helps to distinguish when the filename is identical in all runs |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Study Id | study_id | integer | Integer identifier of the d3VIEW study created to group all submitted pedestrian-protection simulations. |
| Simulations | simulations | dataset | Dataset listing each individual simulation record (one row per impactor position) with metadata linking position parameters to their respective jobs. |
| Hpcjobs | hpcjobs | dataset | Dataset of HPC job records corresponding to each submitted simulation, carrying queue status and job IDs for monitoring and downstream result extraction. |
