.. _auto_simulation_get_header_info:

*GET SIMULATION HEADER INFO*
============================

Retrieves header and metadata from an LS-DYNA simulation by parsing the d3hsp XML file, extracting solver version, termination/timing details, model statistics, and available file paths. Use this worker when an agent or workflow needs simulation provenance or file-location data before further post-processing steps.

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

Tagged: ``d3hsp``, ``header``, ``llm_tool``, ``lsdyna``, ``metadata``, ``simulation``, ``solver_info``.

Inputs
------

.. list-table::

     - Default
     - Required
     - Description
   * - Simulation Id
     - simulation_id

     - —
     - ✓
     - Unique platform identifier of the LS-DYNA simulation whose d3hsp header should be read; select via the remote lookup (dataType: simulations) — required, no default.
