.. _auto_assembly_replace_parameters:

*REPLACE PARAMETERS IN AN ASSEMBLY*
===================================

Replaces one or more named parameters in an existing Assembly with new values, returning the updated assembly reference and the full resolved parameter dataset. Use this worker when a workflow needs to override Assembly parameters (e.g. mesh size, load magnitude, material constants) before submitting a simulation job.

When to use

Tagged: ``assembly``, ``deck_authoring``, ``lsdyna``, ``parameter_override``, ``parameters``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Assembly
     - assembly_id
     - remote_lookup
     - —
     - ✓
     - Remote lookup reference to the target Assembly whose parameters will be replaced; must resolve to a valid Assembly ID on the platform.
   * - New Parameters
     - parameters
     - dataset
     - —
     - ✓
     - Editable dataset defining the parameter replacements to apply; each row specifies the parameter type, name, and new default value — columns are 'type', 'name', and 'default'.

Outputs
-------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - Label
     - ID
     - Type
     - Description
   * - Assembly Id
     - assembly_id
     - integer
     - Integer ID of the updated Assembly after parameter replacement; pass downstream to solver or deck-authoring workers.
   * - New Parameters
     - new_parameters
     - dataset
     - Dataset containing the full set of resolved parameters for the Assembly after replacement, confirming the applied type/name/default values.
