Defining a surface current

You can create a surface current load to define current densities over a surface in a coupled thermal-electrical analysis.

  1. Display the surface current load editor using one of the following methods:

  2. Click the arrow to the right of the Distribution field, and select the option of your choice from the list that appears:

    • Select Uniform to define a load that is uniform over the surface.

    • Select an analytical field to define a spatially varying load. Only analytical fields that are valid for this load type are displayed in the selection list. Alternatively, you can click to create a new analytical field. (See The Analytical Field toolset for more information.)

  3. In the Magnitude text field, enter the current density (units C L−2T−1). A positive magnitude indicates current flow into the surface.
  4. If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears. Alternatively, you can click to create a new amplitude. (See The Amplitude toolset for more information.)
  5. Click OK to save your data and to exit the editor.
