PARSES LS-DYNA KEYWORD INPUT TO GET PUNCH SPECIMEN INFORMATION¶
Parses an LS-DYNA keyword input file to extract geometric and part information for a Punch specimen setup, including the specimen part ID and the node IDs for the punch, blank, die, and flange components. Use this worker to populate downstream material-characterization or forming-simulation workflows with structured specimen metadata.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| LS-DYNA Keyword File | file_input | file | — | ✓ | LS-DYNA keyword (.k / .key / .dyn) input file from which specimen, punch, blank, die, and flange information will be parsed; must be a valid LS-DYNA deck. |
| Specimen PID | specimen_pid | scalar | 1 | ✓ | Part ID (PID) of the specimen blank part within the LS-DYNA keyword file; default is 1. |
| Punch Node 1 | punch_node_1 | scalar | 1 | ✓ | First node ID used to define the punch geometry/reference frame in the LS-DYNA model; default is 1. |
| Punch Node 2 | punch_node_2 | scalar | 2 | ✓ | Second node ID used to define the punch geometry/reference frame in the LS-DYNA model; default is 2. |
| Punch Node 3 | punch_node_3 | scalar | 3 | ✓ | Third node ID used to define the punch geometry/reference frame in the LS-DYNA model; default is 3. |
| Blank Node 1 | blank_node_1 | scalar | 4 | ✓ | First node ID used to define the blank (specimen sheet) reference in the LS-DYNA model; default is 4. |
| Blank Node 2 | blank_node_2 | scalar | 5 | ✓ | Second node ID used to define the blank (specimen sheet) reference in the LS-DYNA model; default is 5. |
| Blank Node 3 | blank_node_3 | scalar | 6 | ✓ | Third node ID used to define the blank (specimen sheet) reference in the LS-DYNA model; default is 6. |
| Die Node 1 | die_node_1 | scalar | 7 | ✓ | First node ID used to define the die geometry/reference frame in the LS-DYNA model; default is 7. |
| Die Node 2 | die_node_2 | scalar | 8 | ✓ | Second node ID used to define the die geometry/reference frame in the LS-DYNA model; default is 8. |
| Die Node 3 | die_node_3 | scalar | 9 | ✓ | Third node ID used to define the die geometry/reference frame in the LS-DYNA model; default is 9. |
| Flange Node 1 | flange_node_1 | scalar | 7 | ✓ | First node ID used to define the flange/binder reference in the LS-DYNA model; default is 7. |
| Flange Node 2 | flange_node_2 | scalar | 8 | ✓ | Second node ID used to define the flange/binder reference in the LS-DYNA model; default is 8. |
| Flange Node 3 | flange_node_3 | scalar | 9 | ✓ | Third node ID used to define the flange/binder reference in the LS-DYNA model; default is 9. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Punch Specimen Info | punch_specimen_info | keyvalue | Key-value map containing the parsed punch specimen metadata (specimen PID, punch/blank/die/flange node IDs, and any derived geometric attributes) ready for downstream characterization or forming-simulation workers. |
