LS-DYNA PARSE PARAMETERS FROM TEXT¶
Parses *PARAMETER keyword entries from an LS-DYNA input file supplied as raw text (accepted extensions: .k, .dyn, .key, .dyna, .inc) and returns a dataset of named parameters with optional percentage-based variation bounds. Use this worker to extract design variables from an LS-DYNA deck before feeding them into a DOE or optimization workflow.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| LSDYNA Input File | file_input_text | textarea | — | ✓ | Full text content of a valid LS-DYNA input file (extensions .k, .dyn, .key, .dyna, .inc) that contains at least one *PARAMETER keyword block; paste or pipe the raw file text here. |
| Solver Type | solver_type | select | lsdyna | ✓ | Target solver dialect for parameter parsing; currently only ‘lsdyna’ is supported — leave at default unless additional solver options are added in future. |
| Constants | constants | scalar | — | Optional comma-separated list of parameter names to treat as constants (i.e., excluded from variation); leave blank to allow all parsed parameters to vary. | |
| Min Percentage | min_percentage | scalar | 50 | Lower bound for parameter variation expressed as a percentage offset below the nominal value (e.g., ‘50’ means −50%); default is 50. | |
| Max Percentage | max_percentage | scalar | 50 | Upper bound for parameter variation expressed as a percentage offset above the nominal value (e.g., ‘50’ means +50%); default is 50. | |
| Step Percentage | step_percentage | scalar | 20 | Step size between min and max variation as a percentage of the nominal value (e.g., ‘20’ means increments of 20%); default is 20. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Parameters | parameters | dataset | Tabular dataset of parsed *PARAMETER entries, each row containing the parameter name, nominal value, and computed min/max/step variation bounds derived from the supplied percentage inputs. |
