Defining the Pack Region

The pack region is of type solid. You associate the individual battery components with their material properties from the physics continuum: the plate is made of aluminum, the busbars and the tabs are made of copper, and the battery cells are made of a composite material definition, which represents the mixture of all the materials used to manufacture a cell.

The walls of all battery components are adiabatic.

To define the pack region:

  1. Click the Simulation tab to return to the simulation tree.
  2. Right-click the Regions node and select New > Region.
  3. Rename the Region 1 node as Pack.
  4. Assign the relevant geometry parts to this region by using a dynamic query:
    1. Select the Regions > Pack node and click next to Parts.
    2. In the Pack - Parts dialog, open the drop-down menu and select Name.
    3. From the middle drop-down menu, select does not contain.
    4. In the right-hand text box, enter coolant.


    5. Click OK.
  5. Assign the relavant geometry parts to the material part groups:
    1. Expand the Pack > Physics Values > Material Part Groups node.
    2. Select the Al node and set Parts to Plate.
    3. Select the Cells node and create the following dynamic query for Parts: Name contains cell.
      16 matching geometry parts are found.
    4. Click OK.
    5. Select the Cu node and create the following dynamic query for Parts: Name contains tab.
    6. Click (Commit Changes)
    7. Add a second query by hovering over the existing Name contains tab query and clicking (Add a new item (Insert)) : Name contains busbar.
    8. Click (Commit Changes)
    9. Click AND and change it to OR using the drop-down menu.
      15 matching geometry parts are found.
    10. Click OK.
  6. Save the simulation.
