Specifying Copper (Ohmic Heating) Material Properties

The properties of pure aluminum are set on a solid continuum by default. Replace this material with Copper.

To specify the material properties:
  1. Right-click the Models > Solid > Al node and select Replace with.
  2. In the Replace Material dialog, expand the Material Databases > Standard > Solids nodes and select Cu (Copper).
  3. Click OK.
Define a field function to relate the electrical conductivity of copper to its temperature.
  1. Select the Cu > Material Properties > Electrical Conductivity node and set the Method to Field Function.
The electrical conductivity expression depends on the temperature as follows:
Electrical Conductivity=26.08109T27/25
  1. Right click the Automation > Field Functions node and select New > Scalar.
  2. Rename the User Field Function 1 node to Copper Electrical Conductivity.
  3. Select the Copper Electrical Conductivity node and set the following properties:
    Property Setting
    Dimensions ElectricConductance
    Function Name CopperElectricalConductivity
    Definition 26.08e9 * pow($Temperature,(-27/25))
  4. Return to the Electrical Conductivity node, select Field Function, and set Scalar Function to Copper Electrical Conductivity.
