REPLACE PARAMETERS IN A FILE¶
Performs token/parameter substitution in a solver input file (LS-DYNA, Madymo, or Nastran), replacing named placeholders with values supplied via a dataset. Use this worker to programmatically inject design variables or study parameters into a deck before submission.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| File | file | file | — | ✓ | Solver input file (e.g. LS-DYNA .k/.key, Madymo .xml, or Nastran .bdf) containing named parameter placeholders to be replaced. |
| Parameters | parameters | dataset | — | ✓ | Dataset of name–value pairs mapping each placeholder token in the input file to its replacement value; see d3VIEW dataset input format. |
| Solver Type | solver_type | select | lsdyna | ✓ | Solver format of the input file — ‘lsdyna’ (default), ‘Madymo’, or ‘nastran’; controls how parameter tokens are parsed and written. |
| Format | format | select | short | ✓ | Field-width format for the output deck — ‘short’ (default, 10-character columns) or ‘long’ (20-character columns); applies primarily to LS-DYNA keyword formatting. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Replaced File | replaced_file | file | Modified solver input file with all parameter placeholders substituted by the values provided in the parameters dataset, ready for job submission. |
| New Parameters | new_parameters | dataset | Dataset echoing the final name–value pairs that were applied, including any defaults for tokens that were not explicitly overridden; useful for traceability and downstream reporting. |
