Assigning Parts

You can add in-house parts or assemblies (which may be linked to other parts or materials in the database) to your BoM. For Sustainability analysis, parts can also be stored as Standard Parts that have environmental data defined in the database.

Standard Parts are parts whose Embodied Energy and Climate Change indicator values have been pre-calculated and stored in the database. These may be parts that are bought in from suppliers, where the part supplier has disclosed the embodied energy and CO2 footprint required to manufacture it.

Standard Parts can also be defined for items that are routinely specified in varying amounts - for example, electrical cable (specified by length), printed circuit board (specified by area), or batteries (specified by mass).

The in-house parts, assemblies, and Standard Parts that your organization has added to the database, along with sample parts and generic Standard Parts provided by Ansys, are available from the Parts tab.

When you add a Part from the database to a BoM:
  • If the Part is linked to other Parts (that is, stored in your database as a linked structure that represents an assembly with components), the linked Parts are retrieved from the database and added to the BoM.
  • Any Materials directly linked to Parts are added to the BoM as material assignments.
    Note: Linked Specifications, Coatings, or Substances are not added to the BoM when you are working in Sustainability mode.
Warning: The Embodied Energy and Climate Change indicator values for Standard Parts provided by Ansys account for average global transportation from the manufacturing facility to the facility that will use the part. If you assign a Transport stage to a Standard Part, the impact of this transportation will be calculated and included in the 'Transport' phase, resulting in double counting. The same applies to in-house parts if their environmental data already includes transportation.

To ensure accurate results, verify whether transportation is already included in the environmental data of the part before assigning additional Transport stages.

When you add a Part to the BoM, you must specify its Quantity and Unit of Measure. For more information, see Quantities, measures, and masses for Sustainability.

To assign a Part from the database:
  1. Identify the location (parent part), and add the part:
    1. Right-click the parent part and select Add > Part
    2. Locate the Part to assign, right-click, and choose Assign.
  2. Specify the part's Quantity and Unit of Measure.
    The units that you can use to specify the quantity depend on the part that you are adding. For example, an in-house assembly might be specified in units of 'Each', a printed circuit board might be specified in units of area, or a Standard Part might be specified in units of mass. For more examples, see Quantities, measures, and masses for Sustainability
    Note: When a part is specified using a non-mass Unit of Measure (for example, 'Each'), additional information about the mass that this Unit of Measure represents is required in the Mass per UoM and Mass Unit columns. For parts stored in the database, if the required data (for example, the part mass in units of kg/Part) is available in the database, it will be retrieved and displayed in the BoM either when the part is added to the BoM, or when it is analyzed. If this data is missing when the BoM is analyzed, you can enter it manually in the BoM and run the analysis again.
  3. Optional: Edit the Name of the part in the BoM.
