*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.

     - 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.
