PARSES LS-DYNA KEYWORD INPUT TO GET UNIAXIAL SPECIMEN INFORMATION¶
Parses an LS-DYNA keyword input file to extract geometric and mesh information for a uniaxial specimen. Given a part ID and node IDs for the extensometer gauge length and width directions, it returns structured specimen metadata for downstream material characterization workflows.
When to use¶
Tagged: extensometer, keyword, lsdyna, node, parse, pid, specimen, uniaxial.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| LS-DYNA Keyword File | file_input | file | — | ✓ | LS-DYNA keyword (.k / .key / .dyn) input file containing the model mesh and part definitions to be parsed. |
| Specimen PID | specimen_pid | scalar | 1 | ✓ | Part ID (PID) of the uniaxial specimen shell or solid part within the keyword file; defaults to 1. |
| Extensometer Node 1 | ext_node_1 | scalar | 1 | ✓ | Node ID of the first extensometer attachment point used to define the gauge-length axis; defaults to 1. |
| Extensometer Node 2 | ext_node_2 | scalar | 2 | ✓ | Node ID of the second extensometer attachment point used to define the gauge-length axis; defaults to 2. |
| Width Node 1 | width_node_1 | scalar | 3 | ✓ | Node ID of the first transverse (width-direction) measurement node on the specimen cross-section; defaults to 3. |
| Width Node 2 | width_node_2 | scalar | 4 | ✓ | Node ID of the second transverse (width-direction) measurement node on the specimen cross-section; defaults to 4. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Specimen Info | specimen_info | keyvalue | Key-value map containing parsed specimen metadata (e.g., part ID, initial gauge length, initial width, node coordinates) for use in subsequent material characterization or calibration workers. |
