*CREATE A MAT_001 KEYWORD FOR LS-DYNA*
======================================

Generates an LS-DYNA *MAT_001 (*MAT_ELASTIC) keyword block from basic elastic material parameters. Use this worker to programmatically author or inject a linear-elastic material card into an LS-DYNA input deck.

When to use
-----------

Classification: **data**.

Tagged: ``deck_authoring``, ``elastic``, ``keyword``, ``ls-dyna``, ``mat_001``, ``mat_elastic``, ``material``.

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Material Name
     - material_name
     - scalar
     - —
     - 
     - Alphanumeric label for the material (maps to the TITLE field of *MAT_001); leave blank to omit a title comment.
   * - Material ID
     - material_i_d
     - scalar
     - —
     - 
     - Integer material ID (MID) referenced by *SECTION and *PART cards; must be unique within the deck.
   * - Density
     - density
     - scalar
     - —
     - 
     - Mass density of the material (RO field); units must match the deck's consistent unit system (e.g. kg/mm³ or tonne/mm³).
   * - Elastic Modulus
     - elastic_modulus
     - scalar
     - —
     - 
     - Young's modulus (E field); units must be consistent with the deck (e.g. GPa or MPa).
   * - Poissons Ratio
     - poissons_ratio
     - scalar
     - —
     - 
     - Poisson's ratio (PR field); dimensionless value typically in the range 0.0–0.5.
