.. _auto_simulation_update_attribute:

*UPDATE ATTRIBUTE OF A SIMULATION*
==================================

Updates a named attribute (e.g. name, description, status, solver version, tags) on an existing simulation record in the d3VIEW platform. Use this worker whenever a workflow needs to programmatically modify simulation metadata without touching the simulation files themselves.

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

Tagged: ``attribute_update``, ``metadata``, ``platform``, ``simulation``, ``simulation_management``.

     - Default
     - Required
     - Description
   * - Simulation
     - simulation_id
     - remote_lookup
     - —
     - ✓
     - Platform simulation to update — resolved via remote lookup; provide the simulation name or ID of the target record (required).
   * - Attribute Name
     - attr_name
     - select
     - —
     - ✓
     - The simulation attribute to modify; choose one of: name, description, solver_type, solver_version, project_id, status, product_type, options (JSON string required), thumbnail (Base-64 encoded string), or tags.
   * - Attribute Value
     - attr_value
     - textarea
     - —
     - ✓
     - New value to assign to the selected attribute; for the 'options' attribute supply a valid JSON string, for 'thumbnail' supply a Base-64 encoded image string, otherwise supply plain text.
