LS-DYNA NOTES TO DATASET¶
Parses an LS-DYNA keyword text block containing node definitions and converts the node data into a structured dataset suitable for downstream ML training or CAE preprocessing workflows. Optionally extracts keyword parameters alongside node coordinates and supports user-defined metadata attributes.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| LS-DYNA Test | lsdyna_text | textarea | — | ✓ | Raw LS-DYNA keyword text containing *NODE definitions (and optionally other keyword blocks); paste or pipe the full or partial deck content here. |
| Parse Parameters | parse_parameters | text | yes | ✓ | Controls whether keyword parameters (e.g. NID, X, Y, Z, TC, RC columns) are extracted alongside nodes; accepts ‘yes’ (default) or ‘no’. |
| Additional Attributes | attrs | textarea | — | Optional additional metadata attributes to attach to every row in the output dataset, specified as comma-separated name:value pairs (e.g. ‘model:v1, unit:mm’); leave blank if no extra attributes are needed. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Nodes Dataset | nodes_dataset | dataset | Structured tabular dataset where each row represents one LS-DYNA node with columns for node ID, X/Y/Z coordinates, optional constraint codes, and any user-supplied additional attributes; ready for ML ingestion or further CAE processing. |
